Product Description
This thingy, that is quite important if you want centered holes when punching, broke the other day. Amazing, considering it is no more than 20 years old - I thought a German quality product would last :-)
Anyway, I made a copy in SolidWorks for a 3D printed replacement. No guarantees as to how well it fits or how durable it will be since I haven't done a test print yet.
