Legos Collection Tray mount for desk or worktable

Welcome to my new design.
This Model i made for my work as i work in a 2th hand legos store we need to sort a lot of those bricks and parts.
We need to collect them and fill bags and a lot of parts where falling off the table and basically making a mess.

This model solves that issue it can be mounted to most desks up to a 4CM thick plate and aligns accordingly to the top surface that way you can throw in the parts without hassle the slide down and fall into a hole specially made to have eithe a polybag hanging on it (see pictures) or you can but collection boxes underneath it no more parts over the floor!

The print is preconfigurated just hit print the size is for H2D however if you need it smaller it can be cut smaller for X1C and others.
The screws must be printed in 100% infill to prevent it breaking when under stress.

i included  square screw hole mounts for those who sanded the hole down too much.
As the holes in the main collection tray where fine on my H2D with Bambu Filament but since i know it might be a bit to tight for some printers you can sand down the hole until it fits the screw more nicely.
if sanding too much and its loose the square screw holes can be put into place aswell on the inside of the handle however this makes the mounting possibility 3 CM instead of 4

Good luck!
