SOMETHING OLD, SOMETHING NEW
Vintage camera collecting and 3D printing go hand in hand, at least in my mind. I have been interested in 3D printing since relatively inexpensive consumer printers entered the market. Replacement parts and custom modifications are not easy to come by. 3D printing allows for these needs to be met cheaply and efficiently.
I currently run a Creality CR-10 and a Flashforge Creator Max. The Creality has a large build volume and the Flashforge has dual extruders with an enclosed build space.
All design work is done in Fusion 360, but other software like Sketchup or Solidworks can also be used.
While, in general, these parts do not look exactly like the original, they are good enough to make a camera functional again.
I have designed and printed knobs, gears, film masks, film adapters, spools, hand grips, and storage products.
