Do you have a 120 film camera? Want to shoot images with the sprocket holes exposed? Want to shoot specialty films that are not available in 120 format? If so, or you just like to play with film, these adapters are for you. This takeup spool winds up 35mm film onto a 120 format spool. The matching 35mm film adapter is at http://www.thingiverse.com/thing:323120. There are two STL files, one with and one without supports. The supports are necessary - the one without supports requires setting your slicer to generate supports. If in doubt, print the one with supports. The supports are easily cleared away with a twist of your fingers. These were designed for the Flyer 6x6 camera developed as a result of the Pinhole Printed Kickstarter project (http://www.pinholeprinted.com) but can be used in any 120 medium format camera.
