Summary

This is a simple base for the FiiO K11 amp/dac. I made this to help keep the amp from tilting and sliding around.

There's divots in the corners for 20mm double-sided adhesive dots. Any double-sided adhesive should work, or you could just set it on top. I printed in TPU, but PLA should be fine too. I would test print a chunk of it to test the height in case it needs any vertical scaling.
