Modified parts for mcmaven's Triple Axis Tourbillon

thingiverse

These are modified versions of parts for mcmaven's excellent Triple Axis Tourbillon, tailored to make printing easier, with looser tolerances and faster results. The new base falls into the latter category, taking approximately 2 hours to print instead of the original 5, which was quite a significant improvement. I broke down some of the original parts into separate pieces for easier printing or shorter time increments, allowing my printer to run for only 1-2 hours at a time without interruption. Printing parts in sections and gluing them together with screws or pins helped keep everything aligned. There are also a few changes because I just can't resist tinkering. In detail: Compact base and Compact base panel make up the new base, designed specifically to accommodate an Arduino Nano. Incablock clip thinner is a slimmer version of the Incablock clip; unfortunately, the original one didn't fit. L1 Balance shaft extra clearance adds a bit more clearance between the balance shaft and the fork pin for smoother movement. L1 Balance Wheel solidified is a variant of the balance wheel featuring solid sides to make printing easier. L1_Frame_Lower modified merges the screw seats and thickens the area where the incablock goes, enhancing overall stability. L2 Frame Lower cylinders {1,2,3} breaks L2 Frame Lower into three parts, allowing for support-free printing of the ends which go into the bearings. The pieces are then joined together using glue. It can be held in place with screws while the glue sets and removed once it's set. This modification also thins out part of the frame to provide more clearance for L1. L2 L1 gear 3 point uses the third screw hole in L2 to make the gear more stable, reducing wobble. L2_Idler_gear_28T_M1 extra clearance adds some clearance between the idler gear and L1. This change prevents collisions with the balance adjuster screws, which sometimes interfere without it. L3 Frame 2 a {1,2,3} and L3 Frame 2 b {1,2} split up the L3 Frames into smaller pieces for shorter printing times and less support. The total print time isn't significantly different. Glue the parts together using 1mm pins to hold them in place. I had some 1mm steel pins from an earlier project; if not, stiff wire can work as a substitute. Finally, speedmotor.ino is my modified Arduino sketch. I used Blender for designing these parts. While it's not ideal for mechanical design, I know it well and can get things done quickly in it. The Blender files are included. Where necessary, I used Loctite Super Glue Ultragel Control to glue the pieces together. Hold them in place for 60 seconds and then let them sit still for another 15 minutes. mcmaven recommends a different glue but unfortunately, it can't be shipped to California where I live.
