snowskate TPU trucks

Updated to reflect V4 & V5 below

OK, so I design things to keep my mind busy. Sometimes I design things that are theoretically practical but implicitly stupid. Every once in a while something comes out of this process that might actually be useful - let me be clear, this is not one of those things. Snowskating is already inherently dangerous.  3D printing trucks for a snowskate is a total idiot move.  

I shouldn't have done it and you shouldn't either.

Disclaimer over.  if you are still reading you can join me for the weekly dingdong club meeting.

Now on to the data:

Main truck bodies are printed with 98A TPU, 8 walls, 3.3mm top and bottom and 30% gyroid infill.  If you have the slightest hesitation about the quality of your print, throw it out and start over.

Backing plates (top and bottom) are Taulman 910, solid print with 16 walls and .2mm. I expect other nylons to function just fine as long as there isn't too much give.  You will almost certainly need longer hardware to get through the TPU and nylon backing plates.

If you have a leash hole on your deck, you can print 2 each of trucks, backing plate top-deck side and backing plate sub-deck side.  If you need a leash mount as well, a TPU print of the leash extension and top-deck leash mount will likely be needed.

Added V4 & V5 recently - changes the paradigm a bit.  Prints without supports but one long stretch will be a little rough for a layer or three.

Main benefits of V5:

Changes the length that each layer rests upon the one before principally along the core flex axis.  Adds significant additional layer length just in the off chance layer separation might happen.  Printed in TPU I would be very surprised if that were ever an issue.  V1 has half as much layer on layer space, and it's seen 10+ 4 hour sessions with no signs of any issues.

V4 version - same as before, but softer

Same benefits as v5, but steeper back-cut giving more flex.  I highly recommend avoiding this unless you are a lighter rider.  At 6' and 17 stone I'm on the bigger side and I can definitely feel things getting a bit too mushy for my taste on V4

A while back, added v3 which seems to have approximately same core lateral strength but includes just a bit more camber flex. Also tested some 95a filament - If I were under 70ks It would probably work well.
