How to Design & 3D Print a Custom Camera Lens Cap (Onshape Tutorial)

I picked up a vintage wide-angle lens off eBay for just £20, but it was missing one critical thing: a front lens cap. Instead of hunting down a generic cover that might not fit, I decided to design, model, and 3D print my own custom lens cap from scratch. In this video, I walk you through the entire maker process: • Taking precise measurements using digital calipers • Planning tolerances and material shrinkage (PLA vs PETG) • Quick 2D sketching to 3D CAD modeling in Onshape • Slicing and printing a snug-fitting final part Sponsor: Huge thanks to PCBWay for sponsoring my upcoming channel builds!
