Calling All Makers: Carbide Community Competition #1


(Apollo Crowe) #1

:raised_hands: Carbide Community Competition #1 :raised_hands:

The Lego Batman movie is coming out soon!
So this first competition’s only rule is keep it Lego themed in any way. This should keep the barrier to entry low, I would love to see these competitions become a weekly event that build our Design and Making abilities by sharing ideas and inspiring each other.

As a note, Schools are a big part of our Carbide 3D Community and they need fundraising projects to build on their Machines, so keep that in mind - if you can share your design file, it will help our kids!

Rules:
Lego theme.

Material: Open

Machine: Nomad or Shapeoko

Tool: Open, (1/16th endmill suggested)

Required Info in your Post:
Photos! The More the better.
A) Materials used
B) Cutters
C) Design software
D) Machine

…And these additional details I would think would help earn votes from the Community but are not required:
E) Work-holding
F) Finishing
G) Sourcing of supplies is often very helpful.
H) Concept Sketch
I) Machining Time
J) Carbide Create .C2D file

Voting will be done with the heart, the post that gets the most likes wins.

February 18th we will tally the votes.

Prize to be determined, feel free to hint at what you would like in your post. :stuck_out_tongue_winking_eye:

For those looking to get started with a test cut heres a Carbide Create file I have tested on the Nomad with a 1/16th square endmill.

This picture might be useful (1 LDU is 1/64-inch or 0.3967 mm)

Also, did you know that the hole in the bottom of a Lego is the right size for an M6 tap?

@atrueresistance

Jorge has something in mind,…
I was going to listen for hints so as to make the prize have some personal significance.
Did you win last time?


#7

I did not, there wasn’t enough time last competition. I like this one it gives me more time.

Do you happen to have an .stl of your Lego Bricks?
…or how do I open the files above? Neither Carbide Create nor Aspire seems to recognize them.


(William Adams) #11

.mcf is MeshCAM.

.stl on GrabCAD: https://grabcad.com/library/lego-brick-2x4-1#!

Fusion Link Sadly, I think I need to square my spindle a bit more. :frowning:

Broke a bit, that is why you get more than one. :slight_smile: Made it all the way to the back side before a problem happened. Does a cutting feed of 10 in/min with ramp set to 10 in/min and plunge set to 5 in/min seem too fast? .01" maximum roughing stepdown and .01" step over with the Dewalt set to 27,000 RPM with a .0393701" bit.



(Jerry Gray) #13

Your feeds seem conservative to me.
I usually start out 50% width and depth and .001" per tooth per revolution with a small bit, but yours is TINY :slight_smile:
Nice job too.

@atrueresistance

What cutter did you use?
I see a picture of very small endmills,…


(William Adams) #15

OpenSCAD for creating any size brick you might want:

I think I have to have a go at this this weekend. But what to make?? The only prize I want is for the touch probe to be realeased :wink:

Overall it turned out really well. The legos fit perfectly with each other as well as real legos. The wood i purchased from the local store. I should of used some higher quality hard wood because the pine had issues tearing but it worked. For work holding I designed holes in the wood and just bolted it to the table. Was very sturdy. This also allowed me to flip the wood and mill the other side and the cuts would line up perfectly with no effort. I hope you like! Hint Hint :slight_smile:

Material: 3/4 inch pine
Cutters: 1/4 2 flute end mill, 1/8 4 flute end mill (purchased both cutters from Amazon)
Design software: Fusion 360
Measurements: http://www.instructables.com/id/DIY-LEGO/step2/The-measure-of-LEGO/
Machine: Shapeoko 3
