Design Approach:

This is a simple, cheap and easy to build case for the Prusa i3. The overall costs of the build should be kept low, so I decided to work with just 3 mm acrylic panels, which are stable enough thanks to the corner pieces. The whole case screws together with 54pcs m3x10mm screws, no glue required. To mount the case to your desk, you can tape the bottom corner pieces to your table. The case then can be lifted completely for printer maintenance. 

Printing instructions:

Printing the parts from PLA is okay, even for higher temperatures.
We suggest standard-settings: 0,2mm layer, 2 perimeters.

Lasercut Parts:

For the acrylic parts, a laser cutter is needed. You can download the cutting files and cut it in your local makerspace/hackerspace.
