With the XL, you had 5 spools. The printer has holders on the side for 3 spools on one side and 2 on the other. The holders can handle 1 or 2 kg spools.
I find the polydryer boxes great for my PETG. I have a Ptfe tube and a female female Ptfe conector and I just put the box on the floor :-)
PLA I just hang on the side.
At one point I had fillament coming out of a waterproof tub from costco, but frankly the polydryer boxes are great. I have at one point had 5 of them on the floor. I wish the 2 pack of 2kg polydryer XL boxes weren’t on back order. I would snag maybe 4 of those. I purchased a bunch of Prusament 2kg spools as Printed solid had a them on sale 5 for the price of 4 with 15% off so it came to about $17/kg.
Of course if one was to plug in 10 polydryers and a printer you would probably blow a breaker.
