About this 3D model

Printed with PLA. Can easily support 10 kg (I tested with 15 kg without braking). All screws are hidden. I used screws with 3.5x50 mm. Shelf size: Thin - 221mm (W) x 220 mm (D) x 15 mm (H) Large - 210 mm (W) x 250 mm (D) x 30 mm (H) Tips to print: When printing the shelf (no need for the support), disable Auxiliar Fan for the last 4 layers.
