About this 3D model

I wanted a solution to store filament in my printing table (two 4x3 IKEA Kallax shelves behind each other). This is, what I came up with, as I didn't want to spend much money on that. The shelf slides on 3d printed parts. BOM: 4x M3 Heatset Insert 4x M3x30 SHCS screw several 4,5mm/35mm screws (front, thicker Kallax side) several 4,5mm/25mm screws (everything else) 1,9cm x 77cm x 30cm shelf, e.g. https://www.hornbach.de/p/moebelbauplatte-weiss-19x300x2630-mm/1060566/ Cheap PETG filament or similar With 4 perimeters and 25% infill, one drawer needs ca. 520g of filament. I used some cheap 7€/kg Jayo filament. Much cheaper than using some kitchen All files fit the build plate of e.g. a Voron V2 350x350mm
