The maker Sandeagle has presented ‘PrintClosure’, an interesting open source project. It is a housing for the Prusa MK4/S printer. The modular design can even be realised on printers with a smaller installation space.
The housing consists of individual components that are connected using printed pins and M3 screws. The developer recommends 3 mm thick PVC rigid foam panels for the back and top, although glass or acrylic can also be used. Special compensator parts are integrated into the design to compensate for material shrinkage caused by heat.
Approximately 2 kg of PETG filament is required to print all parts. The recommended print settings include 2 perimeters and 15% gyroid infill. Due to the sharp corners, the use of brim structures is recommended.
In addition to the 3D-printed material, other components such as acrylic glass plates, threaded inserts for hinges and corners, neodymium magnets and various M3 screws and nuts are also required.
The side parts are attached using M3x10 screws, while M3x16 screws are used to connect the individual parts. M3x25-30 screws are used for the corners. The developer emphasises that not every hole needs to be used, but more screws increase stability.
The 3D print files can be downloaded free of charge from Printables.
