T-Nut (plastic only) for OpenBuilds V-Slot (Customizable)

A customizable t-nut for OpenBuilds V-slot.

This is designed for lighter-duty work and doesn't use a metal nut.

The plastic hole can be tapped, or a screw can just be twisted into it.

Can be customized for any size screw, and any number of nuts, but I've included STLs for a dozen M5 nuts and a dozen M3 (or 4-40) nuts.

If you need more solid attachments, you can use my 10-32 T-nuts (which require small-profile metal nuts) here:
