This is an under-desk A4 tray designed to organize your disks and hold your papers and notebooks.
You might need to sand the edges of the connector part to ensure it can be inserted properly, as the design has been made as tight as possible.
You need to install two supports, one at each end of the set, both back and front.
The tray is printed with PETG, but you can also use PLA or ABS.
I printed it with a 0.4 nozzle using my Ender 3 V2 (no support needed).
Update:
Unfortunately, with a notebook and around 50 papers, it broke from the sliding point. I will edit the design to be permanent with screws and update it within the upcoming days.
