/diy/ - Do It Yourself

>>2814139
It's probably easier to understand this way up.
When printing a big hole (head of the bolt at bottom) and then need to print a smaller hole in the middle of the bigger hole... you cant, becasue its in mid air.
So either :
1) the print fails until something snags somehting else and you end up with a big section of fucked print that might end up as a useable hole once you clean out all this fuzz.
*cough* gridfinity combination magnet/bolt hole in the solid bases *cough*
or
2) you hope your support can reach up into the hole and support the tiny circular overhang, and still be able to remove the support afterwards.
or
3) you hymen it in your design with a single layer across the bolt between head and thread
or
4) you hope your slicer has that feature and can do it right

A combination of 3 and 4 usually works almost all of the time.

picrel is the bolt and its boolean that I import when adding bolts, i make any hymens as needed, I only added them to it here to illustrate.
