Dual rear lens cap for canon

thingiverse

I was struggling with Hooorse's design, since I wanted a single piece It also didn't thread solidly like my usual rear lens caps. I originally printed with Prusa i3 MK3; Hatchbox PLA, 20% infill. slow speed 210/55, 210/55. No brim or skirt I was very excited to use the original, but when I printed and the cap doesn't easily screw onto the lens. Maybe if I ground it down with a file or enlarged the print to 102% it would screw on, but I can rotate the cap approx 1-2 mm before it binds. I' also don't understand why it can't be a single print. I'd rather have a small portion of supports to remove than to have to link the two caps together decreasing strength and adding weight. --------------------------- Updated: 8/3/2018 I attached a file that combines both into a single printable piece. It works well with the exception of the existing attachment issues. When printing, use "support from bed only" and it prints without a hitch.
