62mm Slip-on Lens Cap

thingiverse

I have a series of smaller lenses, for all of which I have step-up rings to 62mm (for my ND and polarizing filters). I needed a slip-on lens cap for these rings, so I built this. No support needed, could probably get away with 20% infill. Generally I have to sand out the inside a bit to make it larger--it's a custom fit for each ring anyhow.
