Prusa i3 MK3/S/+ Name Tag

For those of us who like to name our 3D printers, perhaps as a practical means of identification, for fun, or whatever reason you may have.

Information

This name tag is inserted into the left Z axis cover, which has been modified and will need to be replaced. The name tag itself is removable, and is customizable to your liking. Due to the X axis, the replacement Z cover does not increase the printer's footprint, while remaining out of the way of the extruder assembly. This design has been tested on 4 MK3S printers, with no observed effect on the printers' reliability. As the Z cover on the MK3/S/+ is identical, this design is compatible with all printers in the MK3 family.

Printing & Installation

Text can be added to the name plate directly in PrusaSlicer. However, as additional customization in 3D software will likely be desirable, caution is advised. When sizing the name plate to accommodate larger text, avoid extending it further than 1 cm to the right, to prevent collision with the extruder. Extending the plate to the left is recommended, though at a certain point this will compromise the printer's footprint.

For the Z axis cover, Prusa's standard is PETG, 0.2mm layer height, 20% grid infill (though gyroid is a good alternative). No special settings for the tag itself.

The modified Z cover is attached using the same 2 screws as the original part. The name tag will firmly snap into place. This clearance loosens over time, but it is important not to use excessive force when removing/inserting, as this risks compromising the integrity of the printed part around the screws. If the parts were extensively modified, check the extruder clearances after installation.

Left Z axis top cover has been modified with an extension to accommodate a name tag insert.
