This is a 8mm film projector of an endless track.https://www.youtube.com/watch?v=cy_mY1iS7DA I custom gears from Gear Model For 3D Printer Print Settings Printer: Creator Pro Rafts: No Supports: No Resolution: 0.18 or 0.08 Infill: 15% Notes: I print a High-Resolution gear1. I print parts with normal reslution but that one. Post-Printing Creating Circuit This is a list of electronic components(in Japanese). motor Tamiya 70190 Mini Motor Multi-Ratio Gearbox (Gear ratio 5.1:1) LED OSM74E56F1A Schottky diode 1S3 33Ω resistor Switch Single pole double throw You have to create a circuit as shown in the figure below. Assembling Projector Please see this page that is assembling instructions of the projector. (Take the time to read) I prepared both ai file for laser cutter and obj file for 3D printer of case. You can choose either one. ( I recommend using ai file.) If you use laser cutter, the thickness of the board is 2 mm. I confirmed 3-bladed shutter isn't need, so I don't upload it. You need to prepare a ready‐made loupe and schafts. I use (x15 Lens diameter: 20 mm / maximum diameter: 31 mm) ETSUMI E-203 (in Japanese) and Tamiya 70105 3mm shaft Creating Films You have to prepare film. The film long is 67 frames. If you don't have 8mm film, you can create original film using OHP sheets.This software creates film sheet from serial number image.(Drag and Drop) Then, print it by 2d inkjet printer, and cut it using template.ai by lazer cuttor.
