Magnetic bit holder, symmetrical. Should fit most cordless drills.
Designed for ø10x2 mm magnets. Sometimes sold by Lidl.
The magnets are embedded, pause the print at the top of the magnet holes and insert the magnets. The print will lock them in place.
To avoid the magnets flying away and sticking to the hotend it might be a good idea to use some ca glue to fix them in place.
This model is very similar to jldmag and other magnetic bit holders but this is a new original model.
Google "embed hardware in 3d print" for instructions on how to insert the magnets.
