YG300 Projector Lens Cap

thingiverse

This is a Lens Cap for the cheap YG300 Projector found on Chinese eCommerce sites. It is held in place with a rubber band (that can also be used to keep the cap on top so you don't loose it while in use. I got mine on Aliexpress (when it was on sale), but I recommend getting it from Banggood or eBay. Mine did not come with a lens cap which sucks for a portable projector, so I made one! I thought about making a press fit cap, but that might put extra stress on the lens and would wear out fast. I may eventually post a V2 that is press fit, but the rubber band is good enough for now. I designed this in Onshape. Here is the link to the design. Print Settings Rafts: Doesn't Matter Supports: No Resolution: 0.1-0.3mm Infill: 5-20% Notes: If you have a nozzle 0.5mm or wider the extrusion width might make it fit a bit tight.
