PLEN Playground - Forum

I am having trouble printing Plen2 barb.stl
Most of it prints ok but one of the 2 tabs that lock the chin into the upper body will not print. Please share your printer settings used or suggestions. I am new to 3D printing. I have new M3D Pro printer and have tried different settings and filament types but the one tab doesn't print properly even using supports setting.
I would appreciate any suggestions.
