2020-02-09 (Su) SocketSetStack

My quarter-inch sockets are not precision engineered hardware. They are inexpensive tools in an even cheaper case, so I do not expect they will have tight tolerances. I would prefer to measure their actual dimensions than rely on what they're supposed to be. As it turned out, the conversion was close. 0.25 inches is equal to 6.35 millimeters, and I measured 6.3 millimeters.
Wider than a straight calculation

When I printed the first draft, I was disappointed to find that the part was smaller than expected. It should have been snug inside the socket, but there was lots of room to wiggle. Before that, I tried printing with a raft, but that caused a failure that I don't understand where the part would not adhere to the base layer.
Way too loose

The second draft, printed with a brim base, also featured a wider hole in the center to accommodate a 1/4" bolt. I did not render the full model since the spacer cylinder at the top would not be necessary. With the second draft, it fit with very little room to move because I added a variable to the code that would expand the model a bit to overcome the reduction. For the next model, I will have to add something, like a taper, so that the prints will apply some friction to the sockets.
Close fit, but not snug
