Second World War KDF dimple shifter knob

This dimple shifter knob was originally installed in the Volkswagen Kübelwagen (Typ82) and the Schwimmwagen (Typ166) just before and during the second world war. Originally the part has an M10 thread, this pack of 3 includes three versions of the knob:

1- The original M10 thread (10.2mm diameter)
2- The original M10 thread (10.4mm diameter)
3- (smoothed) The original M10 thread (10.4mm diameter)
4- An alternative space to fit an M10 nut

The original dimple shifter knob from the Kubel / Schwimmwagen was used as inspiration to model. As such, the dimensions of the knob should be close to 1:1, the logo dimensions are as close to 1:1 as possible.

• Updated on 20-02-'24 - After some feedback from an expert on these knobs, I added a smoother version. If you're looking to get a replica as close as possible to the original, your best bet is this new smoothed out version.

Since this part has tiny features (the logo and the thread) it is best printed on high resolution resin printers. As such, these printer settings concern that method. If you still want to print on FDM, it is recommended to use the version with the space for the M10 nut, and play around with the 'hole expansion' settings in your slicer.

Print the model in a 30 degree angle with supports connecting to the underside of the model. If you're using chitubox, you should be fine using small support connections.

Try printing in 0.05mm layers heights, and switch to lower layer heights if you experience surface artifacts.

The 10.2mm threaded version might be just a tad too tight, therefore a 10.4mm diameter threaded version is included.

Make sure you take a soft brush and brush the threads with some alcohol (or water, depending on your material) after printing and before thoroughly washing the print. Curing could best be done for around 30 minutes given the thick parts.
