This is a pill counting / part sorting tray like a pharmacist uses. The lid on the side of the tray lets you pour the tray contents in one container and the parts on the side of the tray into another container. Here is a similar version on Amazon.
Updated to include a tray with a left handed spout in addition to the original right handed tray.
Needs three M3x16mm socket head screws for the hinge. You can probably get away with two if you really want.
Overall size is 202 x 163 x 30mm. Can be changed in Fusion 360 to fit larger printers if desired.
Print the side lid upside down with supports.
Printer: Ender 3 Pro w/ direct drive
Rafts: Yes
Supports: Yes
Resolution: 0.16-0.2mm
Infill: 15% or higher (I use cubic)
Shells: 2+
Material: PLA/PETG (Anything will work)
