MODULITH Prusa Core One Kit

Storage that lives right under your printer.

Uses space you already have. Printed rails and brackets mount under the Core One, and MODULITH 240 drawers slide in below. The 240 length matches the Core One build plate, so every rail prints in one go.

Go taller with 2H feet. Print the 1H feet for a low setup, or step up to the optional 2H feet and fit up to 3W-2H of storage under the printer.

Fill it with something useful. The Core One/MK4 Tool Insert gives every tool from the Prusa box its own spot in a 240 2W-1H drawer.

Looks right at home. EdgeLabel faceplates keep the handle clear of the table and look great next to the Core One, especially printed in Prusa orange.

GEN2 is now MODULITH. Same system, same compatibility. Print only what you need, snap it together with QuickLock, and rearrange or expand your storage anytime.

INSTRUCTIONS

Going taller? 2H feet instructions →

Touchscreen tip: the Core One screen can make 0.5H drawers fiddly to get in and out. It is only held on by magnets, so open the door and gently lift the screen a little and the drawer slides right in.

PRINT SETTINGS

• 1H feet: 4 perimeters, 25% gyroid infill

• 2H feet: 4 perimeters, 20% adaptive cubic infill

• Everything else: 3 perimeters, 15% infill

Good bed adhesion keeps the rails straight. If prints lift near the edge of your plate, clean it with dish soap and water and try an adhesion promoter.
