Sometimes when 3D printing you get an under extruded print. That's where not enough plastic comes out and the model isn't fully bonded together or is 'squeezy' to the touch. This happened to me due to a blockage, and thinking that this was a good opportunity to take advantage of an 'easy' to cut up model I thought I would make this into a ruin. Armed with Dremel with mini circular saw for cutting I hacked into this one. An hour later covered in plastic and with plastic in my eye (even though I was wearing protective goggles and mask) I vow never to do that again. That plastic is hard, hard, HARD!
The result is passable, or will be once I glue things back together and fill some places.
Moving forward, however, does anyone have some suggestions of easy to use software to erase parts of the building STL and smooth/close the shell back up. I tried Meshmixer but that was a pain, I don't want to have to spend a day learning how to use it if possible.
