120 FIlm Clip for P6*6 Pinhole Camera

thingiverse

This is an accessory for the P6*6 Pinhole Camera: http://www.thingiverse.com/thing:157844 I discovered that film sometimes unwinds when unloading the P6*6 (doesn't appear to be brand specific). This can cause nasty light leaks from the top and bottom of the roll, ruining several negatives at the same time. I previously advocated for gluing a small block of foam onto the inside surface of the uptake spool cavity, but I find that the foam absorbs glue, becoming too stiff to allow the insertion of an empty spool when loading. This clip is inserted with the empty uptake spool (despite the pictures of a full spool). As the roll of film is used, the clip loosely holds the film snug against the spool, allowing unloading without the light leaks and fogging ( For more information, read film_clip_instructions.doc in the downloads section).

Instructions I the best luck printing these clips with one perimeter and 50% or greater infill. Print them at the same vertical resolution as your camera, to ensure that there is a positive engagement and the clip stays in place. If it should get knocked down inside the camera, it should still work. The three sizes are labeled "25"., "50", and "75" for (now) arbitrary reasons, Consider them small, medium, and large respectively. I find the smallest size ("25") works just fine. The P6*6 has a small lip inside the body of the camera that prevents the clip from rotating during use. You will want to remove the raft and clean up the bottom edge before use. If the clip is too tight on a full spool of film you risk twisting off the spade that drives the film as you wind it. I advise printing a spare winder assembly and keeping it in your kit.
