Empty Spools piling up?  Decided to whip up a simple solution to stack them in a corner.  Press fit, Adjustable height, 4 Wall, No infill to speak of.  This one was printed out of ABS with the Cap upside down for minimal supports.  Flip it over if you want a cleaner dome and don't mind extra supports.  None of the rest need supports but if like me you use ABS, your going to want a brim for sure but you could use anything you like minus Carbon or Glass fibers.  Lastly, a shout out to Bambu Lab for some High Temp Filament "REFILLS"  Please?
