Xcelite Hex Nut Driver/Setter Holder - Magnetized Base
And here I thought there was no way someone had taken the time to make a holder for these.
The premise of this remix is pretty straightforward. I wanted to add magnets to the base so these don't move around in my tool box. Did I do a perfect job, no, but it was done quickly. The model is designed around using 8x3mm magnets. On my Ender3 V2, this wound up being press fit with no adhesive required, YMMV.
