I know there are plenty of other designs, but I wanted to try and create my own. I wanted something for under the table where I could throw filament scrap away. I printed on the Flashforge Adventurer 5m on the stock settings with Overture PLA. Supports are needed. 

I also added magnet holes, two sets on the rail and one set on the drawer. The magnets I used were 8x2mm from amazon. 

Screws holes based on M4 size.
