Cannondale Topstone frame hole cover cap
Little cap on my frame was missing, a quick print with TPU made the trick!
A hole inside the design will make it (i hope so) easyer to remove if it need to. It is a really tight shape, a bit hard to install. But this time i wont loose it.
15% infill (or even less if possible). Print it upside down, maybe with raft or brim (easyer to remove).
I tried different orientation, upside down still the best.
I hope it will be usefull for someone els ;-)
