TNUT bar for glueing (for 20x20 profiles)

I needed to attach, only sliding in, a box to my Ender 3. So I went for a remix of the t-nut gerneratd with the customize from 'anthem'. Thanks for sharing.

This T-Nut bar can be glued direclt to the part and has just enough clearance to slide the part in postion along the profile.

Happy printing.
