Lego Man Head bored out
Remixed from the one referenced.
Bored it out using SW to save material.
The top of the bore is a 50 degree cone so it doesn't need support internally.
Set your overhang threshold to 55 deg.
200u layer height
Only 8 to 10% infill required (use lines/zigzag)
Takes about 4h to print out using S3D
I did it on an Ender 3 S1 using PETG because that was the only stuff I had in yellow.
v2 is the mega bored out version which is hollow all the way thru vertically. You may prefer this one.
Enjoy!!
