Description
Inspired by several long shifter designs on the market.
Largely the same profile as the factory Miata (MX-5) NA/NB shifters. Made longer and larger to better suit the driver's hand. 80mm tall and about 40mm diameter (widest point).
Should thread on with hand, and friction is large enough to keep it from spinning. Opening is flared to sit flush against the shifter rod.
The “m” logo can be either printed using multi-color, or you can print the insert version in two filaments, if multi-color is not an option.
Test fitted with the insert version. Printed on Bambu P1P with PETG. The insert had to be horizontally shrank by 0.1mm. I suggest test printing the logo with different tolerances to test fitment to your liking.
All the filed were made by Solidworks. For some reason the Top plane is not the same as in the 3mf file. I think it's obvious which orientation to print these in. No supports are necessary.
Print settings:
Layer Height: 0.2mm base with variable layer height
Perimeters: 5
Infill: 30% Gyroid
Bottom/Top Layer: 2.5mm
Support: None
