Made these for tahustvedt's Ursa (bear) - Fully printable Monster Truck https://www.thingiverse.com/thing:2299884 to try and make a long lasting printable CV joint for diff's Seem to handle testing so far, ended with the one of the diff gears blowing up. Steering lock to lock is easier and less drag. I used 1.75 filament for the pin and it seems to be ok, did plan to use a 2mm metal pin. Can be replaced with out splitting the diff. 9-7-17 Added the parts to change the drive shafts from Gearbox to diffs New axles for the diffs with better centering of the balls for cv's (0.8mm longer) and 0.3mm more clearance for the spider gears (bearing 0.3mm closer on long axle) as i found mine to tight on the side gears with the new 4 spider diff. 9-7-17 New diff input gear. might be easier to assemble and stronger. 11-10-17 New ball ends, V2 longer and radius in the bottom of the groove. 12/5/17 Updated to latest versions Using tig welding wire 1.8mm for the pins
