Lens cap for projector

I bought the cheapest Chinese projector available on Amazon. I didn’t expect much, but for the price it actually performs very well.I decided to design a lens cap to protect the glass. Mine measures 29.7 mm, and I suspect most budget models share the same lens since they’re likely produced in the same factory—so this should fit many of them. I’m sharing the design in case it’s useful to others.I printed it in PETG. The fit is intentionally snug so it stays securely in place, yet it’s still easy to remove. If the fit isn’t ideal for your unit, you can adjust it using your slicer’s scale tool in 1% increments. Just make sure your lens is around 30 mm by measuring it with a caliper first.Preferisco questa rispostaBoost Meboost me please!
