Wanted to angle my speakers up a bit so i made these. I did the first 12 layers in pla for the double sided tape to stick to, and then manually switched to tpu for the rest of the print. Since the ams can't feed tpu you have to pause the print at the layer you want and then swap the exterior spool filament by yourself. Or just print the whole thing in pla if you want. (Just make sure to remove the cange filament line in the slicer preview!)
I also made a guide for lining up the feet to my Argon Audio Forte mk2's but it obviously won't work well with differently sized speakers. You'll have to eyeball it then.
