3 Axis Gimbal

A 3 axis gimbal I designed for a test fixture at work. The original had printed corners and machined sides due to our printer not being large enough to print all the sides. I did a test print of the bearing hole in ABS with a 0.4mm nozzle and standard Fine settings in Cura 2.6 on our Ultimaker 2 and the bearing was a nice press fit.

Stainless steel pins are used for the locking mechanisms. They were machined with grooves for 4 C-clips but I have listed external push rings which will work although you will only be able to install 3. Be sure to round off at least the one end of the pin so it will slide easily into the locking hole. Stick a block under the outer locking ring plate of sufficient height for the locking pins to clear the next ring by about an 1/8" and slide the inner locking ring up against the wall and seat in place with the external push rings. We reamed the locking pin holes to 0.128" and got a nice sliding fit which would stay back out of the way when in free swingin
