Chevy Sonic Shift Knob

thingiverse

I created a custom replacement shift knob for my Chevy Sonic that showcases a collectible coin. Designed specifically to accommodate a dollar-sized coin within a plastic case, this unique feature protects the valuable item from scratches and damage while it's nestled snugly inside the shift knob. A threaded insert enables the knob to be printed without any supports, making it easier to produce. To ensure its durability in scorching summer temperatures, I opted for PETG material when printing my custom design.
