Tipping hooks
Hotfix:
Reinforced back wall so that it does not bend. Fixed one hook so that it didn't tip too much.
Added new version. The pitches for wall mounting are the same.
PLA, I recommend Inffil 20%. The supports are only on the printing plate.
After print you must remove connection on upper side tipping hooks with back wall.
Update:
I removed connection on upper side tipping hooks with back wall and I reduced infill on 15% into gcode.
