I made it from 9 slots to 4 on both the tray and the holders for the rockwool.
Made another version from it to add labels with Nimbot D101 label machine and one that should fit generic machines.
Printed it in Translucent PETG (Just because I wanted to lol), and the bottom tray in grey PETG.
Thanks to the original creator!
