Lens Cap

thingiverse

This lens cap is designed for lenses with 49mm and 52mm filter threads; a 58mm version may be added later. It is printed using PET and ABS, with PET providing better spring action although ABS works too (PLA untested). The model prints as one piece, with some parts lightly fused together. Gently bend and pinch to separate connections. For customization, the spring section begins at 2.4mm, while the sliding section starts at 1.25-1.4mm.
