Simple cover for skywatcher newtonian telescope 200 mm (8") for use after colimating.
Printing
About 152 grams, PETG recommended, Nozzle 0.6 mm (usually [much] faster than 0.4mm nozzle), Layer height 0.3 mm. No support needed, wall loops 3 (maybe more if you print with 0.4 mm nozzle).
If you think the cap is too loose, you can apply adhesive tape to the inner diameter and adjust the fit to your needs.
