Brings back memories...
An Optimist is a sailing boat class for children starting from 5 years.
My test print was printed with PLA with support, 0.1 layer and 2 shells.
Next I will try a print with PETG.
PETGs very interesting characteristic is that it's much more watertight in comparison to PLA, it's harder and it's not getting soft untill 70°C (158 °F) .
PLA is getting soft at 60°C (140 °F)
PETG is printing awesome on the M2, no warping.
Show off your prints!!!
