3D model description

Living in China, I couldn't find a supplier for a "Fork Cork", so I whipped up this design for the underside of my Rockshox Pike steerer tube. Works nicely so far!

Printed the top and bottom in PETG for some durability & weather resistance.
Printed the middle/wedge part in a flexible TPU.
Designed for an M6 bolt & 10mm nut.

Not sure about the durability... If the wedge is soft enough, you shouldn't need to over-tighten the bolt to get a secure fit. Over-tightening will definitely crack the caps!

Plan is to put lightweight supplies inside & forget about it (cash, patch kit/tire boot, quick-link, nitrile gloves, etc)
