This is a dedicated chuck stopper for the K02-50 4-jaw chuck included with the Makera Carvera / Carvera Air 4th Axis module.
Main uses & benefits
Consistent, repeatable positioning The stopper acts as a physical reference surface, allowing you to push the stock to a consistent depth/position inside the chuck. This is especially useful for stock under Ø15 mm, ensuring repeatable clamping even when you swap the stock multiple times, which helps prevent dimensional variation.
Faster setup Simply insert the stock and seat it against the stopper to locate it quickly. This can significantly reduce setup time and improve workflow efficiency. The default thickness is 3 mm, but you can adjust the Z scale to 3D print it at any thickness you want.
Modding idea
By editing the original STEP file, you can also create a centering jig for flat plate stock, like the one shown in my video (02:17).
Boost MeIf this helped, a Boost would mean a lot. It helps me keep sharing useful jigs like this.
