1/25 Scale Tiki Head Shift Knob
I modified the Tiki Tap Handle by Shapespeare by scaling it down to 1/25 scale and adding a base with a 1.2mm opening. This allowed me to use the model as a shift knob for my 1/25 scale hot rod model kits. You can also scale it up for larger models, though I wouldn't scale down as it was already hard enough to paint at 1/25 scale.
I think it goes without saying this should only be printed on a resin printer :)
