Re: 3D Printed CAT 963K Track Loader w/Raspberry Pi Control
I made some progress over the holiday weekend and actually started printing a few parts. Since 76 are going to be required, I started off with some track link/pads.
   I am happy with how they are turning out. they will need a little bit of finishing work before painting, but they link together well and work with the 3/16" clevis pins I chose to use. I also printed the outer part of the motor mounts. These came out nice, and fit the motors well. They seem to be plenty strong, too.

I'm excited to see some parts printed up, everything looks killer! Yet another build thread that threatens me to sell some toys to buy another one~ A printer of course.

Re: 3D Printed CAT 963K Track Loader w/Raspberry Pi Control
Managed to get a few more parts printed and some hardware ordered. I now have over half the tracks printed (38 per side) and the hardware to link them together.
 The front idlers are printed also. I chose to print them in halves to make it easier to get the concave dish to print well. 2mm dowel pins are used for alignment and then they are bonded together with acetone.    The drive sprockets were also printed. They bolted up to the motor hubs perfectly, and line up well with the tracks. There is a dummy planetary unit that will hide the screws and provide a more scale appearance.   I was also able to finalize my cylinder designs and get an order placed with Magom for the hydraulic system. I am looking forward to getting that stuff in so I can finalize my main chassis design.

Rexracer 19,
Can you post a link to where you bought the 3/16 grooved Clevis pins please. Followed the link over on the D10b3d print build but they do not seem to have them any more. Appreciate any help locating the hardware and with you sharing the build. Cheers Trackerman.

No problem. I picked mine up from McMaster-Carr. "Grooved Clevis Pin w/Retaining Ring"
