Description
Update 2020-12-11: I goofed up the export of the single-piece stl, the chevron was missing its slight taper. Should be updated now if thingiverse decides to function for once.
Update 2020-12-14: Added a variant of the shaft and teeth where the teeth are recessed/slotted into the shaft. Removes need of guide blocks and gives the teeth a flat bottom to allow better print orientation but likely at the cost of a slightly bigger gap to fill after assembly.
Available in a single piece but for ease of printing and increasing overall print quality I recommend printing it in parts.
The guide blocks are to make sure the teeth are center-aligned when affixing them in the original version of splitting the parts. The slotted variant should overall be better.
Preview was printed in parts, sanded, glued and gaps filled.
