My friend Azraen was able to test print this for me before I go on my trip! They had no issues or warping with it so I've made it available on my Ko-fi - https://ko-fi.com/s/422ed9c2e7
It's currently scaled for a 26cm doll but you could scale it and make some minor edits to the base for magnet size. Right now, it's set to use an 8x2mm magnet.
I've also set up a Cults3D account for anyone who prefers that - https://cults3d.com/en/users/EverydayDollyDomes/3d-models
The original Wavelength head is there, as well. I'm hoping to test the 2.0 version of that, soon, but it's apparently...too high res or something? IDK but Chitubox hates it so a more experienced friend of mine is trying to knock the file down without it turning out too crummy >>' I guess it makes sense...compared between my original and the new one...it definitely has a LOT more detail.
