Pinball Leg Bolt Soft Socket Insert

This is a replacement liner insert for the 9/16" soft socket commonly sold by pinball parts vendors.

Soft sockets are designed to install powder-coated leg bolts without scratching the finish—but the liners tend to wear out quickly with regular use. This model replaces the original liner and restores the socket’s protective function.

Printed in TPU at 0.2mm layer height with 20% infill. 2 Wall loops, 4 top shell layers, 3 bottom shell layers. 

Update (5/16/2025): Newer version with tapered walls to enable a tighter fit in the socket and easier fit on bolts.
