Thread holder

The print pictured was printed in PLA

No supports are needed, print with the front, facing down on the build plate.

Use double-sided tape to attach it to the table

To create the screw holder on the back I super glued and m3 screw in from underneath and threaded on a bolt. I used a bolt handle found here:

to make removal easier.
