simple drawer

This is a simple rail for a drawer made out of a plastic storage box. It creates a lightweight and cheap drawer for your desk, increasing the space of your desk.
I have added the sketchup model, in case you need to adjust the height of the storage box edge.
From printing perspective, I have used PLA with 1.2mm walls and top/bottom + 20% infill and no support. This is a lightweight content and I have considered this to be enough strength. For larger boxes, you may consider printing it using stronger materials (PETG for example).
