I would love an explanation of how you fit the motor / electrical side of this for the RC plane if you had the chance. Or let me know where I could easily find that information. I’m interested in building something similar now that I see your awesome work.

Oh no server issues are no good.
Anyway here is the Carbide Duck back from the digital abyss. I had some troubles exporting the DXFs from Fusion 360 into Carbide Create, but did include all .F3d, DXFs, and CC files in the zip.

The best way to read up and learn about electric power for RC planes is via Ed Anderson’s online book “Everything You Wanted To Know About Electric Powered Flight” As you dig thru it you will also find a pdf version of most of the content. There is some science to the madness for a nice running system.

@SLabuta, I love these little guys:
I think they have 1/32" endmills in up to 1/4" flute length.

Planetary Gear
Made this on the Nomad, it’s quite small at 75mm x 75mm (roughly 3" x 3") so it’s a fun project to run on some scrap wood. I used some 1/4" thick maple, but the dimensions are not that important, you’ll end up with 3 layers once assembled.
I had to start by researching Planetary Gears, got lost in the math of trying to calculate gear dimensions, tooth pitch, tooth count, etc. Ended up finding an ~okay~ gear simulator here, mixed those results with some photos, and edited that in photoshop. Once I had the 8 gears (don’t want to use the word ‘designed’), more like ‘hacked’ together I then imported into Carbide Create.
The results where then tweaked, top and bottom holders were designed which resulted in this…
The design for the top and bottom (right side of the model) were constrained to what hardware I could find, pocket holes for the nuts and screw heads. I have mixed feelings regarding the use of tabs in this project. Assembly took longer because of the tabs, next time I will probably remove the tabs from the model and use lots of tape. However if you scale this design up to a larger size the tabs may be a better route.
Assembly was easy, in photoshop I was able to eyeball how the gears would fit, and had reduced the size of the six planet gears which resulted in a nice loose fit once CNC’d.

This may end up as my goto project to use up scraps left over from other projects. This entire planetary gear could end up as one planet-gear within a larger planetary gear… hmmm.

Oh boy, you are really not helping me put my Nomad gear lust under control.
Thank you for your entry !

Here’s the Rummikub set again. Thanks @Julien for the notification.
This set can be disassembled into four racks and these holding tablets (see left in the next image).
The racks fit onto the pins on the tablets to make the assembled box somewhat stable.
The number tiles are finished with color now …
… and while it wasn’t meant to look like that, I like how the color has found its way into the wood fibers occasionally:
This actually brings me to the question, how you guys manage to get those super clean edges when coloring engravings?
I grounded the tiles with linseed oil, let it dry, applied the color (overlapping the edges), let it dry and then sanded off the top. However, as you can see, while sanding the top I also worked the color into the wood at some places.
Overall, I learned a lot of beginner’s lessons with this project. Most importantly probably that cutting pockets parallel to the wood fibres can cause very large fibres to tear out (at least for pine), so that I started to rotate the design or the stock in order to prevent this.
Here are the files:

Thanks for the update @nlichtenberg. What you get in those color tiles is “bleeding”, i.e. paint/pigment finding its way into the wood fibers (some woods are more sensitive to this, depending on their grain). One trick to avoid this is to apply a coat of shellac/varnish/lacquer/anything transparent really, to seal the areas you just cut. Let dry, and then apply your paint, and sand like you did.
Yup, I’ve been there. Either cutting at an angle or using a downcut endmill takes care of that problem.

2.5 days to go before the deadline, don’t be shy and let’s see those last minute entries!
(last time, @duexx took the “last minute” concept very literally by submitting 3 minutes before midnight!)
I can’t believe @Vince.Fab asked that question but had nothing in mind

Hi guys, the project I’m posting today is the sole reason for buying my Shapeoko’s and modifying them extensively. I documented upgrading smaller so3 to linear rails and ballscrews last summer but never actually followed up on how it performs, so this is how the machine looks today and it’s been a real pleasure to work on.
This project is actually a product that I’ve been developing for the past couple months. Coronavirus slowed down the progress as I’m having difficulty finding a company that would manufacture carbon fiber parts for me, but the majority of machined parts are ready. What I’m working on is a motorcycle cafe racer/street tracker kit for a 05-08 Triumph Speed Triple. The objective was to design a simple but visually appealing kit that would allow for quick change of style, by simply swapping mounting plates with seat units.
The design was heavily inspired by ‘Confederate motorcycles’ giving it industrial look, but also making it fairly easy to machine on the desktop cnc.
Don’t know if it’ll count as two entries or just one, but I’ll post both products that are part of the same kit.
#1 Minimalistic subframe with interchangeable seat units.
All the parts could technically be redesigned to be cut on the laser, plasma, or water jet, but machining them makes them look much nicer.
At the end of the post I’ll show how they all look mounted on the actual motorcycle.
#2 License plate mount.
This will also use a modular design, allowing for either - mounting a license plate behind the sprocket, next to the rear wheel or extend all the way past the rear wheel. The second option also comes with the integrated turn signals.
Option 1
At the time of posting don’t have access to my workshop, so couldn’t take a picture with the actual license plate mounted in this location.
Option 2
Finally, this is how all the parts look like installed on the motorcycle.
And also the unfinished street tracker seat.
Sorry for some of the pics being pulled from the IG stories and other taken with some crappy cameras, but haven’t had a chance to properly photograph entire kit yet. Hope you guys like it. And if anyone would like to follow my cnc struggles my IG is: bk1photo
There’ll be much more cnc content soon.

Hi @BartK
Very impressive…I can only imagine the countless hours that went into this, it’s just beautiful and a testimony to why the Shapeoko rocks! (and you do too)
So it kills me to have to mention this, but I suppose you cannot/do not want to share the associated design files, which was one of the rules of the challenge 
Is there part of it that you could share so that people could benefit from e.g. your toolpath strategy, feeds and speeds, etc? in the spirit of validating the entry.

Thanks @Julien
I honestly missed the part where we have to upload the project and the tool paths, although that makes sense. The only part of the project that I can create separate file for and upload so others can see my technique would be those clamps.
They’re slightly oversized to fit onto a carbon fibre tube and allow for adjusting the angle at which license plate sits behind the wheel. I can make a separate Fusion360 file for it. If that’s not enough then ‘ohhhh well, happens’ lol

I’ve been known to bend the rules before (and I’ve been called a pushover for doing it, ha!), so as far as I am concerned, if you do make the effort to share a sample file and tell us about your approach/tips to cut shiny parts, it will be valid. Since the entries will be submitted to vote anyway, people who think otherwise will be free to not vote for you

Cool, I’ll make a post about my workflow and will post the file as well.
Hi, everybody,
I made a decoration for my house. (a frame)
I put it in two times… I looked for a shape that I really liked, in the shape of waves, but a little too pronounced for what I wanted to do.
So I made a frame with a simpler shape, but that I could fix “a soft wood” on it. that the cladding be constrained in both directions of the wood. In French we say gauche…
Then I had the idea to introduce a led ribbon inside. to make it more fun, and more trendy 
the frame is in 3mm medium, “soft wood” in walnut. I made all the drawings on rhino, and made the machining on CC.

Very cool !
I am most definitely stealing this idea for making flexible wood surfaces:
Thanks for your entry Vivien.
