Short 16mm Film Rewinds

thingiverse

When editing 16mm motion picture film, you need a way to wind it between reels. Normally this is done with a pair of large geared cranks called "rewinds". But what about something small and portable for animation, film cleaning, handmade films, etc? I designed this short rewind to comfortably handle 100ft daylight spools up to 400ft reels. Print 2 to make a perfect editing setup with a Moviscop and splicer. Print **Short_16mm_Rewind_allparts.stl** for one complete rewind, or print the included STLs for individual components. The stand is designed to accommodate a large "A-clamp" so you can clamp it to a desk. The OpenSCAD design files are included, so you can modify it easily. NOTES: - The only non 3D-printed parts are: M4 x 25mm bolt, washer, and nylock nut for each knob. - Not compatible with "keyed" reels that have a round hole, sorry. - Prints without supports. I used .2mm layer height. ASSEMBLY: - It's all friction-fit, so sanding or adjustment may be required! - Drive the main shaft backwards into the flange until 30mm protrudes from flange to shaft tip. - Push the flange into the hole in the base. (I needed to sand mine to make a smooth bearing surface.) - Attach the knob to the crank using the M4 screw/washer/nut. - tap the crank onto the back of the shaft to complete the rewind. - Now clamp it to the desk and start editing!
