Original Prusa MK4/S Enclosure

Introducing the Original Prusa Enclosure: Modular box for your 3D printer.

Enclosures primarily help stabilize the internal environment and raise the ambient temperature, which is crucial when printing with materials such as ASA, PC-CF, PP and others that tend to warp. We have also prepared a number of add-ons to meet your specific needs.

The Original Prusa Enclosure is delivered unassembled as a building kit.

More about the enclosure:
If you choose the option with LED Strip and/or Advanced Filtration System, we will automatically add the required PSU for $37.99 (already included).
The PSU can power both the Advanced Filtration System and the LED Strip at once, so only one PSU will be added.
All add-ons can also be purchased separately here.

The Original Prusa Enclosure is an accessory for your 3D printer that houses your Original Prusa i3 MK3S+ or MK4 and provides a stable printing environment. The enclosure helps reduce odors from certain materials, lowers noise, can be equipped with useful additions for increased safety and/or the ability to run the printer in public spaces, and helps print advanced materials due to the passive heat coming from the heated bed (prevents warping). There is enough clearance above the printer inside the enclosure to mount the MMU2S unit.

Everything is included in the package, including plastic parts, so you don't need to print anything yourself. The only exceptions are the optional LCD supports and handles (seen in some pictures) and the silver PSU bracket. If you want to mount the display outside the case, you can simply print the LCD supports at any time. Assembly instructions are available online. A 3D printer is not part of the package.
