I have made this quick and easily printable dual controller stand (high version) for my two 8bitdo SF30 Pros. You’ll probably need a little bit of glue to put the top and base parts together. With my printer/filament it was a tight snap fit but those are extremely random to get right. I would use glue anyway, wouldn’t want to risk this to fall apart with the controllers on 😉
3MF files are with separate meshes, if you like to change some proportions or something.
STL files are merged so you can drop them into your slicer.
