Threaded Stick

Designed in Fusion360 for my pal, who needs it to screw into a foam ball to hold things...

Printing:

I'm not sure yet... try 10% infill and maybe support and adhesion layers because it's fairly tall.

**Added G-code file with the top screw part set to have 100% infill, to make a stronger screw.

If it won't load this can be done manually:

Can be done in Prusa Slicer via Height Range Modifier (load STL in Prusa and right click > Height Range Modifier > set layer range 151.24 to 203.24 mm > click gear icon > Infill > set to 100%).
