Use it every day when I make copy. Had to size it up to 110% in order for it to fit the coffee filter, but that was nbd!

Works great! Initially I printed the whole set in PLA, but every time I pulled a roll of filament out of my AMS I would forget that the desiccant holders were in the centers of each spool and they would inevitably fall out. (User error- no fault of the model!). After a couple of them broke open after a fall, I elected to re-print them using PETG, which seems a bit more able to take a beating due to my forgetfulness. (Again, no fault of the print... totally the fault of the printmaker! :-) )

Worked like a charm! Appreciated that the slot is large enough to fit a variety of different sized phones so everyone in my family can use it!
