Just a Nut and Bolt

This is a bolt I designed it works well printed with 20% infill.
I printed it at 0.1mm layer hight but I think 0.2 would work just fine.

Tips when printing

print slowly the small parts of the bolt can be knocked over easily
print with a raft or something similar the bace is small and can peel easily
ABS is recommended but soft PLA would probably work as well

If you print this please leave a comment on what was good and also things I could improve.
