Telescope Dust Cap (90mm tube)
A push-over dust cap for a telescope tube measuring about 90mm outside — the tube size of the common 80mm short-tube refractors (their maker sells 90mm tube rings for them, which is as close to a published OD as these scopes get). Bored to 90.4mm: the 90mm tube plus 0.4mm clearance, an easy push fit that still stays put. 12mm skirt, 2.4mm walls. Verify your tube with a tape before ordering — tube ODs are not standardised, and the same design cut to your measurement costs the same. Prints face-down, no support. PETG for the skirt's spring.
