This is a two-piece clarinet stand which folds up so it can be stored in the bell of the clarinet inside the case. I feel that this is a strong print and I've used it with my clarinet, but obviously use this print at your own risk.
Note: I've added 3 versions with different tolerances for the screw thread, so you can find the right version for your printer and preferred layer height. Smaller layer heights can probably get away with smaller tolerances. Also, if the tolerance seems very tight, you could force the screw in, slowly rotating back and forth, to create a very snug and well-screwing fit.
Attribution: I was inspired by jasonemock's Clarinet stand model. I wanted to see how well my SV06 Plus could print in place, so I designed my own version of the clarinet stand.
For first time use, fold the legs up into the screw. Sometimes they need a bit of persuasion. The legs have been designed such than they cannot fold down too much, so don't force them down beyond roughly 20 degrees. Then fold the legs down again and screw the inner model into the outer model. Your stand is now ready for use!
To store the stand, simply screw the inner model out, fold in the legs, and screw it back into the outer model. Store inside the clarinet bell.
The author remixed this model.
I added chamfers to the base of the feet to prevent them from flopping down when picking up the stand. If the stand is stuck to the clarinet bell, picking it up will not allow the feet to fall inwards, but because the feet still stick outward, you can easily put the clarinet and stand down again.
I also made the feet a little broader and thicker for more support of the clarinet. I improved the hinge design so print-in-place parts have no overlap and will come apart easily after printing.
