I have completed two prints of “the wrench” in PLA. Both parts function properly. All I did was use a small adjustable wrench to hold the socket adapter and turn the printed wrench in the loosen direction to break the ratchet free. There wasn’t much resistance and the same gcode was used for both colors.
I used slic3r with 4 shells, 4 top/bottom layers, 30% infill, and 0.1 mm layer height. I never print at 0.1 mm, so the wavy appearance on the brown wrench (not as visible on the gray, but still there) is something new to me. Also surprising was the lack of fill around the text on the gray wrench while the brown was just fine. It is probably a small difference in filament diameter between the two that I won’t bother myself with too much.
Now I need to take over the world with my 3 in-lb rated wrenches.
When printing at .1mm height or something with a lot of small details and quick non printing moves I’ve learned I need to turn down the retraction settings. With so little volume being pushed it takes a bit to recover and over retracting can lead to spotty fill.
The printer is a modified Mendel Max 1.5 with an e3d v5 hot end.
I have the slicer settings in the post. Looks like the only core setting I left off is speed. I had speeds set around 40mm/s. Print time was just over 4 hours.
