This is a combination of a simple clamp and stand for filament rolls. It's a flexible system, so you can use it just as a clamp/clip, or you can use it just as a stand, or you can use it as the combination. Print time is around 20 minutes (6.5g of filament) and the parts can be printed without supports.

When the printing is done, make sure to remove any stringing from the screw and threaded hole before inserting the screw. Tested with Bambu Labs and eSun spools, but the design should accommodate other spools as well.
