Under-bed Tray - Nozzle and Barrel Organizator Holder

I saw simple trays on friend's printer and I'm designing my own trays adapted for one of my printers, geeetech i3 proB. I think it will work on any printer with M8 threaded rod, distance from floor 20mm.

Holes for 18 nozzle M6 and enough space for barrels.

• I've add small piece which I used to check dimensions. You can use it to see if it fits on your printer before printing full tray.
• Some more pictures with distances to bed.

Please comment if it fits on your printer or any suggestion, work still in progress))
