Cup Holder Compression Insert

Update (v15): Has had walls tapered for outward flex for true spring-like compression. Also has cutout for cell phone.


Adds a slight taper to a straight walled cup holder.

This one is specifically designed for 3.55" SS from Amazon (sold under many names): https://www.amazon.com/dp/B06X8Z2KVJ

Print upside down. Brim recommended but can get away without one.
