This is a storage box I made from the newer inland spools. There are other makes but none of them were big enough for the newest Inland PLA and PLA+ spools so I remixed these to fit. You will want to print 4 of them and I used M4*8 screws.+
I was able to make all 4 fit and print successfully on a 220x220mm bed. VERY tight fit but works. I also printed these much lower quality and little infill because I wanted to see how quickly I could get them to print. With the settings below it was just under 9 hours.
This is a remix from https://www.thingiverse.com/thing:398515
