This is a button that can be 3d printed that's adjustable. This could potentially make getting clothes on easier for those to can't use their hands with buttons too well.

Note: this needs to be printed out of TPU filament or some other really flexible filament/resin. For this, you don't need an enclosure. From my research, my Voxelab C2, an Ender 3 clone, can get hot enough for this, but you might want to add a low friction nozzle (if you don't use one already).

For best results, you might want to do 0.1mm layers, as the base is 2.5mm tall.

There's a premade button with 8 extensions attached to it (the one that's not in the folder,) but if you want a shorter or longer one, you'll need to take the 2 files in the only folder here and put them together in software to get the desired result.
