Lathe 3-Jaw Chuck Spacer for Short Stock - Spider

thingiverse

This tool is designed to space out short stock for use in a 3-jaw lathe chuck's turning or facing operations. The 3/4" wide piece flexes over the jaws and features a center hole, which can be threaded for further outward adjustment if required. Additionally, it has three set screw holes for fine leveling adjustments. Magnets can be pressed into these holes to hold the tool in place against the chuck's body. The minimum grip diameter is approximately 5/8", and this design fits jaws that are 3/4" wide. It works well on a 6" 3-jaw chuck, although it may be loose but not rattling on chucks with narrower jaws. To use, print the tool flat using ABS filament through a .5-mm nozzle, 25% infill, 3 boundary layers, and a 4-layer skirt. Allow it to cool before removing it from the Kapton tape-covered heated bed. Finally, clean any rough edges and slip it onto or off the chuck as needed.
