1952 Plymouth Gearshift Knob

thingiverse

Gear shift knob for "3 on the tree" 1952 Plymouth enthusiasts, also compatible with 1952 Dodge, DeSoto and Chrysler models. Printing tip: This design looks best when printed with the large end facing downwards and the small end upwards. For optimal results, use a 50% infill setting, enable support material with a 50% overhang threshold, and create a 2-layer raft. Post-printing instructions: After printing is complete, tap the knob with a wrench to secure it in place using a 5/16" - 18 threads per inch. 07/03/17 update: A new STL file has been added featuring a gearshift knob design that closely resembles the original.
