M68x1 threaded dust caps, male and female

M68x1 threaded dust caps, male and female, for astronomy.

These threaded dust caps are useful for astronomy cameras, telescopes and adapters. This thread size is often used on telescopes such as Zeiss, Baader, ZWO, Askar, etc.

I print these dust caps out of PLA+ and have found that the threads print nicer in PLA+ vs PETG and that sometimes the threads are so fine that they don't fit as well with PETG. YMMV. Try enlarging/reducing the X/Y axes by 0.5% if they are too loose or tight.

I'm uploading many sizes that I've used on my various telescopes and cameras.
