math 3d models

I think the math is good, but if you find an issue before I can print one out, please let me know in the comment section. Also extruded a logo or two in a leg of the new holder (Volvo, Freightliner, Peterbilt and Kenworth). EDIT 02/06/2021: Added...

I got lazy with my coordinate math at the end. You can see some deviations in openSCAD's rendering, but it gets washed out in the slicer. Not worth the extra time to perfect it. I commented the various layers for easy manipulation. For example, if...

... up to a 84T spur gear. Theoretically, it should fit an 86T 48 pitch gear - based on the math - but I have not checked. ...With a large number of the brushless motors available today, a smaller spur is generally necessary to hit the appropriate FDR.

Kudos to Ian Oliver for sorting out the mildly tricky maths before I had to think about it, but he would like it known that he had nothing whatsoever to do with the ugly code that I wrapped around it. ... We found that printing at 0.2mm with 10...

Yes, 4 multiplied by 4 equals 16, or using numbers 4x4=16, just do the maths. Some people are clever enough to figure this out by themselves, whilst others need assistance with this equation and just need a little reminder. The logo is 25mm high...

I have done test prints and the math checks out. Details to sort out now are the non-printed hardware. Yes, you cannot print the whole thing. You need some reliable parts (aka bolts that won't break) and some wood (_I_ don't want to print 2...

Due to basic math incompetence, I accidentally made a 5 chamber nozzle box. Oh well! Well, if I ever need the pink splatter nozzle nobody ever uses, I've got a spot for it. Unlike the little plastic cases the nozzles come with, you can't really...

... parts are printed at 100%. I maxed out resolution for the given diameter, so it is still sliceable in Simplify3D. Other slicers are able to scale it down, but you may get issues with very thin walls if you go too low. Category: Math Art

... This allows to connect the parts in the correct 72° angles needed for the structure. The STL files contain two sizes, for 3mm and for 6mm foam boards. No glueing required, the structure can be easily disassembled for storage. Category: Math Art

Please keep this in mind when trying to fit a fat HDMI into the top port. Before I got my hands on the board, I had to figure out the dimensions by using ASRock's stock photos and using math to figure out approximate distances.If you have any...

This is a fun little project to assemble. You'll need six 2mm diameter 14mm long metal rods for the joints. All parts are built using my STEMFIE OpenScad library: Stemfie_OpenSCAD If you want to download the original STEMFIE parts you can get them...

... The motor spacers are 2mm and 8mm if you want to do the math for your motors. The 16x16 plates are sized so that you can thread 2mm screws in without needed a backing nut. ...They are there to protect the boards in the event of a bent prop.
