Community challenge #16: Lego-style (closed)

OK - I’ve been at it for several days with this challenge. I’m a complete newbie/green bean here but it’s been quite fun and learning so much. I’m not finished yet and will post final pics later but figured I would add to this amazing forum.

So my idea stems from always having a hard time finding my tools so I clearly needed to hang this up near my SO3. So instead of just using pegboard, I decided to make a lego wall to hang the parts.

I designed the lego’s all in Carbide Create from the industry standard Lego Sizes… I needed a few base plates to hang on the wall and then several pieces to hold the things I would use to hang the tools.

I’ll start with my key learnings so far - which have been way too numerous but I think that’s part of the challenge and learning.

  1. Cable drag - I just have the standard SO3 and thought I followed the instructions to a T, but as you can see from this picture, the cables drag too much in the back and it threw off the machine while cutting so I ended up not having as many pieces as I’d designed. But I added one more cable tie in the back of the machine and it does not drag any more and should not get caught anymore

  2. Workholding - here is where I seem to think I’m getting better but everytime something new happens. I have 3d printed many different size clamps but I either had them too close to the cutter or in the way of the Sweepy. I also was trying to fit the biggest size I could on the SO3 vs. just wasting some wood on the side. I also now have double sided tape that I should use if I’m cutting to the max.

  3. Precision - I first designed my piece to be 14.3" square and just cut it on my table saw, thinking I would be “close enough” to 14.3" so when I turned it over and cut the front, it would be close enough… But even just being a tiny bit off threw off the back. So the next time I had had the machine cut two 1/4" holes that went into my baseboard that was symmetrical so that I could turn it over and just push in two 1/4" bits to get it aligned exact the second time when cutting the other side.

  4. Carbide Create - I learned so many things trying to get it both designed and create the toolpaths.

a) I’m still struggling for a good way to pick lots of things at once without having to click each one while holding down the shift. I found that if I grouped some of the common circles for the cuts, then selecting them would be faster to make the tool paths
b) I was hoping to use the 1/4’ bit the most but the first time I designed it, the space between the outer wall and holes was less than 1/4". But then I read more on this forum, and just created an artificial outer box where the cutter could cut, and then made it around 50% faster. So learning how to offset to make cuts was an important learning for me
c) Carbide Create seemed limited to me at first, but when I really started learning it, there is really a lot of good stuff built in (centering to last object or stock, offsets, boolean, etc…)

  1. Random disconnects. I’m still having them but Carbide 3d team has been awesome in helping me try to isolate it. I was making all my cuts with one .nc file but learned that even with a disconnect, it would not lose the zero point, so I could just do another .nc file without the cuts that were completed. I’m confident I’ll get the random disconnects fixed soon.

Here is my completed base plate:

And here is the first part of hanging tools. I just used a small nail into one of my lego pieces.

My tomorrow project is to stack a few of my bricks together and then cut squares in the top so it can hold my CNC bits and then drill some holes to hold the allen wrenches. I hope to expand this out with another base plate and hold my headphones and eye glasses. It’s all painted red/black to match my wall cabinets.

More pictures tomorrow. And any ideas/recommendations/tips would be hugely appreciated. I’ll upload all the lego parts later too - they actually work and stay together (if I take all my learnings into account).


That’s what I am talking about! Thanks for the early sneak peek.
The red and black colors work very well I think, that should make for a pretty cool workshop space when this is all done, make sure to post a picture of that!

Can you post a pic from the back of the machine? There is definitely too much length there, you should not have those loops visible at the bottom (or did you maybe fix that in the meantime?)

That’s where side clamps like the Gator Tooth and Tiger Claw are handy, they allow you to have the top surface completely free for the cutter/Sweepy to go as far out as required.

Give painter’stape and superglue a try, I find it to be superior to double-sided tape, cheaper, and it is well suited for regular S03 work area (it becomes awkward to use for very large pieces, so XXL users may not use it as much as I do, which is all the time)

That’s a best practice for precise double-sided jobs so it will come in handy quite often.

Just in case you missed it , there are two drag box selection modes: when dragging from the top left to the bottom right, it will select all objects that are completely within the box. When dragging from the bottom left to the top right, it will select all objects that are at least partially within the box. This second mode can turn out to be quite useful, say if you want to select a series of objects that are aligned, but with other objects in between them; if you can find a location where you can draw a vertical or horizontal line touching only the objects you want selected, you can use that mode.
The other obvious tip is to select lots of things and then remove things by holding the shift key and clicking on them. And then again there are designs where you will just have to painfully hand pick the selection, and then grouping is great to only do it once.

Looking forward to seeting the completed project!


Thanks Julien - very, very helpful guidance. I’ll send a pic of the back of machine later as I do think something still might be wrong

I’ll look into other workholding devices as you recommend and will try painters tape and Superglue too.

I did miss the way to select multiple items depending on which direction you go. Where do you find all these type instructions? I had a hard time figuring out how to pan around after zoom and the forum helped me there, but would be good to know where to go for all the specifics of the software.

So here are more pictures.

Here is the way I cut squares to hold the CNC bits

And then mounted on the wall plates with my holder for the allen wrenches

Here is the near finished pics - notice my workbench if red and black so made the lego’s match…

I plan to add the Carbide C logo somewhere soon.

Again, I welcome any feedback and advice.


Here are the carbide create files. Now let the real help and advice come. Thanks

Lego Wall Carbide Create (168.5 KB)

And here is the link to the CutRocket website:


The only resource I know of is this series of tutorial videos:

They were made a long time ago so CC evolved since then, but most of it should still apply.
I am not aware of a full-fledged user manual, but maybe @WillAdams knows. He is also the best reference for all things Carbide Create :slight_smile:

That is a great workbench you got there.

For Carbide Create tutorials and didactic resources in addition to the videos we have:

Firstly…I am so jealous of your idea…looks amazing. As I look at it, I just think…how can you get rid of those nails?

So I thought maybe to use this

If you are worried about the strength, you could probably put a nail through it. And you may need to put two to get the right height.

Then there is the other circle, which might also work great


Again, these are just all unnecessary additions, because I love what you have done, but you did ask how you could take this to the next level.

Btw…The other option, would be to use Lego Heads as the pin to hold the spanner

Oh…and I agree with Julien…great workbench



This project was inspired by Russian Matryoshka Dolls, also called stacking dolls or nesting dolls:

Smallest box with a U.S. Dime for perspective


The smallest box is just big enough to hold one original LEGO brick, and each box maintains the proportions of a standard LEGO brick.

They are machined out of solid pieces of walnut and finished in Watco Danish Oil and a coat of Johnson’s Paste Wax. The interiors are flocked to give them a “jewelry box” look.

First step was to design the lid and basic dimensions. (Note that Box 4 never got built. I didn’t have enough wood, nor did I have an endmill that would reach deep enough to pocket this box):

Second step was a “build sheet”:

Box 1 Bottom

Box 1 Lid (bottom side)

Remove lid and pocket a dogbone into the wasteboard

Flip the lid over

Machine the studs

Box 3 Bottom (I love walnut swarf!)

Box 3 Lid (bottom side)

Pocket a dogbone into the wasteboard

Flip the lid over and machine the studs

Box 1.c2d (85.3 KB) Box 2.c2d (98.2 KB) Box 3 Base.c2d (75.4 KB) Box 3 Lid.c2d (75.7 KB)


Beautiful boxes. I assume some Lego enthusiasts might use them to store their favorite… Lego bricks.

Legoception…what a fantastic idea !


Nice job of flocking also…what did you use?


I used Suede-Tex fibers and color-matched adhesive. The company goes by two names -
Donjer and Flockit. Super easy - just brush on a generous coat of adhesive, blow on a heavy layer of flock, and don’t touch it for 12+ hours. Here’s a couple of stock photos:



I use Flockit…that’s what I figured!

Anyone rushing to submit a project? 24h left!



@Julien, you triggered me with this post. I hope you are happy :stuck_out_tongue:
Glue is currently drying. The evening will tell if I can submit something…


Okay, I can’t completely finish this one before the deadline, but here is my very space efficient …

Lego Spice-Brick

We recently got these flasks to store spices and tea, which finally lead to this idea.

I designed a simple box, with an elevated bottom, so that the top of the flasks (including the cork) would end just under the top of the box and glued everything together. I finished the round inside corners of the side walls and extensions of the bottom with a chisel to get 90° corners.

Glued 3 layers of plywood discs to the corks of the flasks, and that’s basically it. Initially, I had two layers, but the brick didn’t look right then.

Will have to do some trimming at the sides because I messed up measuring the thickness of the plywood :shushing_face: and then I’ll oil or spray color it. And @Julien, I’ll be perfectly fine if this isn’t accepted for vote in this unfinished state!

Decided to leave it as it is an just put on some oil.


Very creative! Definitely a valid entry, thank you.
It also doubles has a kitchen mini-game, “Guess which one is the pepper” :slight_smile:


That’s a really clever idea! What are you going to use to glue those corks on? I’d imagine they’re going to take a lot of torque in use and the glue will need to handle sheer-forces. Maybe a stainless bolt / washer / nut hidden in the lego?

I used regular wood glue for now. After two hours I was able to close the flasks and open them by grabbing the wood part and carefully turning and pulling.

The glue is supposed to be dry and at its full strength after 48h. Will see if it will stand a non-careful opening of the flasks.
Otherwise, your idea is definitely an option!

Or: You draw it, you spice your soup with it!
