Prusa MINI Enclosure V3

Features:

• Size: 445x445x445mm / door: 330x330mm

• Removable door

• Chamber Fan support (optional)

• LED kit support

• Spool fits inside

Design Approach:

This is a simple, cheap and easy to build case for the Prusa MINI. It is the smallest form factor possible for fitting the MINI into a cube shaped case (44 cm), even the filament-spool fits inside. 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 30pcs 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. The front door is also wide enough to fit the whole printer through it when needed.
