GuerillaBeam LED projector - slide holder

thingiverse

GuerillaBeam makes it possible to create strong, adaptable, and mobile image projector devices. These devices can easily fit any 35mm lens and a wide range of flashlights and speedlights. The devices also support common 5x5 cm slides with a thickness of either 2mm (Agfa CS) or 2.5mm. The powerful threads on the device measure 53x3mm and will securely attach any 35mm lens and LED lights. An open-source extension tube is available for creating custom parts. Slots are placed inside to allow embedding fresnel lenses measuring 48.5mm x 38.5mm x 0.5mm, as well as color gels. A top slot is also provided for enhancing projection performance using a collecting lens. For more details on purchasing these devices or building them yourself, visit http://gbeam.de (this website has English options). The project files are typically printed with a 0.8mm wall thickness and approximately 23% fill density. A recommended layer thickness is 0.1mm; however, it can be increased to up to 0.25mm if you're in a hurry. Printing requires the support material for accurate dimensions on slide slots. If support material isn't used, an irregularly shaped slot results.
