Rectangular T-nuts aligner

Model originally uploaded to Thingiverse at https://www.thingiverse.com/thing:2631236.

These T-nut adapters made to hold rectangular nuts from Anycubic Kossel package rotated inside the extrusion.

Version 2 is much faster to print but a bit more difficult to use.

I've used those while reassembling my Kossel Linear frame.
