A Sturdy Metal Housing for Your MK3S Mainboard
Give your Prusa MK3S electronics a clean, durable housing with the Blurolls Metal Mainboard Enclosure. Designed for the Einsy Rambo 1.1a mainboard, it combines a formed sheet metal body, built-in mounting standoffs and a removable louvered cover.
Whether you are rebuilding your printer or replacing its electronics enclosure, this metal housing offers secure board mounting and convenient access for maintenance.
Built-In Standoffs Keep the PCB Clear of the Metal Base
Integrated mounting standoffs support the mainboard above the enclosure base, maintaining clearance beneath the PCB.
This keeps the underside of the board from touching the metal base and helps protect against short circuits caused by direct contact. The standoffs also provide dedicated mounting points to hold the board securely in position.
Rigid Sheet Metal Construction
The formed sheet metal body provides a sturdy structure around your printer’s control board. A textured black finish gives the enclosure a clean appearance that complements the printer frame.
Louvered Cover for Ventilation
The metal cover features multiple ventilation louvers that allow air exchange around the electronics while keeping the board enclosed.
Removable Cover for Convenient Access
The separate cover makes it easy to reach the mainboard when inspecting connections, adjusting wiring or carrying out maintenance.
Prepared Interface and Cable Openings
Dedicated openings accommodate the intended board interfaces and cable routing. For modified printers or third-party boards, compare the product photos with your existing setup before ordering.
