Open Telecine and Mounts

The following parts have been created using OpenSCAD: motor mount, freewheel, freewheel mount, 100mm shaft, extended motor connector /w clip, and extended motor connector w/ thread.

The photo of the desktop shows the motor mount being build by using a 2D outline in LibreCAD, then extruding into 3D with OpenSCAD, and finishing additional customization using constructive solid geometry (http://en.wikipedia.org/wiki/Constructive_solid_geometry).

A flanged bushing was used for the freewheel and mount. The hopes are that this bushings will provide a small amount of friction, and keep the film tight. Second, it might serve as a way to eliminate the motor on the reel with film (i.e. not the uptake reel). The rewind function can still be achieved by swapping the two reels. The trade-off become lower cost and more work versus higher cost and less work.



This part was created by using only open source hardware and software: Ubuntu (similar to Microsoft Windows and MacOS), gimp (similar to Adobe Photoshop), ReplicatorG, LibreCAD and OpenSCAD (simular to AutoCAD), and MakerBot.
