When everything is assembled and powered up, the modified MINI+ sits raised on four angled printed legs, with the filament spool and the power brick tucked beneath the chassis. This printed upgrade from Prusa 3D takes up less room on a desk and keeps the printer's extras tidy in one spot.
Putting it together involves partially taking apart the lower extrusions and fitting leg brackets onto the aluminum rails. Wiring gets extended so the rocker switch and a USB port can move to the front-right leg, and cables run through channels built into the frame. The runout sensor is remounted along the side extrusion, and the spool holder sits horizontally under the main chassis. Assembly calls for an electric screwdriver, hex keys, wire strippers, crimp connectors and a butane torch, with cable ties securing the brick in its underside bracket. STL and G-code files are available for download.
The legs are the visual highlight: black structural extensions with hexagonal cutouts, cross-bracing and a textured pattern, dressed up with orange trim and matching orange plugs set into the cutouts. Removable orange trays slide underneath the bed carriage, and PTFE tubing feeds filament from the low-mounted spool up into the extruder. No swivel is needed on the holder, since differing tensions keep the spool seated by its edges, spinning freely.
One open question remains: the maker wants to look into whether the stand ends up more or less silent than the printer resting on a concrete slab. Testing so far has covered installing the flexible steel plate and loading filament from the under-slung spool.
