EF-M Lens to EM Camera Adapter

Primarily FDM, but if you only have access to a resin printer and have a handle on minimising shrinkage, it should work. My late Dad's EOS 300N camera is part of my antique camera collections but, when he passed, my sister decided my nephew would be able to use the lenses with his camera. 5 years on, I've finally gotten around to getting a lens for it but, oops, it was listed as an EF fitting, but was actually an EF-M. Lenses are spendy, the seller claimed it was the right one, the site allowed them to. AI, hey? Meh, it happens. So, as the camera isn't really part of my active camera kit, and simply a keepsake, to remember my dad's love of photography, an adapter plate it is, then. It's a totally vanilla adapter, no automation connections so, if you print it for actual photography, it'll be manual everything. Also, print it in plack with pretty thisck walls and high infil. WARNING: While I have printed this, I haven't verified it as optically working. It's solely for display purposes, my dad's camera, with a lens on it to save a costly mistake.
