1/2 Dovetail Nut for 1/4-20 Sliding T Nuts

This is a dovetail bar (½ 14 degree) that takes a Flat T-Track nut which you can source at Taylor Toolworks.

I really like these because:

1. The load on the printed part is all compression, making them very strong.
2. The Taylor nuts are relatively inexpensive and snap fit into the dovetail bar.  No glue required.
3. ¼ 20 is a common size, so easy to find mating hardware to make your own knobs or purchase.
4. No need to buy T-Track, just us a ½ - 14 degree dovetail bit and cut your slots directly into wood.

I'm printing these with PLA, 4 perimeter walls, 85% Gyroid.  This is 2 grams of filament and a 9 minute print.   For reference,15% cubic with 2 perimeters is 1.4g of filament, 7 minutes to print.
