I wanted a device like the Priezor LOM that is 3d printable, affordable, and most importantly, available (the LOM is out of stock)
I print in PETG with a 0.6 nozzle, which takes ~70 minutes with my stock Prusa Mini+.
Basically, print the parts, insert the audio jack with a couple of wires pre-soldered to it, Then use M3 screws n nuts to put it together. Wrap your magnet wire around it as many times as you please (shoot for at least 100, probably?), then solder each end to to the aux jack wires.
The author marked this model as their own original creation.
