3D Printable in-ear headphones / earbuds (for 10mm drivers)

Introducing: Chronic SleepBuds

For as long as I can remember I've been fixing wired headphones, from broken cables and plugs to broken speaker coils (yes, those too, and in headphone speakers) always keeping a suppy of parts so I could frankenstein a pair of functional ones together.
Well, I used to, since the advent of glued-shut in-ear headphones things are looking pretty bleak if the cable breaks right next to the earbud itself. Recently the pair I used to get to sleep broke, so here's the generic in-ear headphone casings I designed around the 10mm drivers that left me with. They're as small as possible to hopefully make side sleeping possible (and because I have small ears canals), designed to fit the universal size eartip that the generic Xiaomi accessory earphones come with.

CAD included so you can adapt it to whatever silicone eartips you have.
