This is a new(3-4-19) single piece version for large bed 3D printers. You will need a 13" / 330mm or larger bed. It is designed to fit a Rosewill/Best/Flexzion/Yobo food dehydrator. It holds up to two 1KG spools. You can also stack the reisers to hold additional spools. With this mod, you don't need to destroy your food trays to fit a spool. This dehydrator sells for about one third the price of the exact same filament dryer unit. Supports for the lower edge recommended.

Design Alteration Notes:
Added a single spool riser, and adjusted the height of the two spool unit. The single spool riser now adds 66mm height, the dual spool adds 132mm. This is a little taller than before to allow most 2kg spools to fit even without a tray in the base position. Basically I wanted to add height in full spool increments so if someone wants to stack a lot of reisers they will never run out of space. as a consequence if you just print one reiser it will have a little extra space. This space could also be used for some type of spool support / tray option inside the assembly. I also shrank the bottom inner lip 2mm after a report of some issues fitting the extener on top of a flexion tray. Apparently it fits the flexion base ok but its a minor change.
