Art Pro Audio Magnetic Mount

Print in either PETG or TPU. Use 100% infill. PLA will break don't bother.

2x6 ø10mm x 2mm depth magnets needed. You could get away with just using 6 magnets if you want to stick it do a magnetic surface like seen in the pictures.

I included some files for modding in case you want to attach it somewhere else. The full enclosure won't be a problem because the amp has a max power draw of ~1.8 watts.
