The Core One+ moves fast, and a light table shakes with it. This rack gives it a heavy, stiff base and puts the five MMU3 spools on a deck above the printer.
Design
- Frame: Dexion slotted angle, braced with OSB panels. Four levels: a base, a middle shelf, the printer deck and a top deck for the filament spools.
- Mass damping: a 400 x 400 mm concrete paving tile bolted under the 15 mm OSB printer deck. The extra mass absorbs the racking forces from fast moves.
- Levelling: four M8 threaded rods with printed PETG foot caps, for fine levelling on an uneven floor.
