This is a very quick and dirty round version of the hexy honeycomb coaster, therefore I call it circly honeycomb coaster.
Thanks for the original idea!
Outer diameter is 93.25mm.
PS: The one shown in the picture is a special big edition which I made for myself, this can not be downloaded.
This is printed in two parts, or if you have the option to print multimaterial you may print this in one go.
I don't know if scaling works, probably not if you are going smaller. The design is made for a 0.4mm nozzle with an extraction with of 0.45.
