What a prusa mk4s frame tool holder is

A tool holder that clips onto the side of the MK4S aluminium frame, which is about 6 mm thick, with slots for the Prusa hex keys, a nozzle wrench, a spatula and flush cutters. It has a 6.2 mm clamp slot 25 mm deep with a small snap bump, a 120 × 30 mm tray, 2.5, 3 and 4 mm hex holes and a 45 × 15 mm cutter pocket. Print in PETG on its back.

The CORE One is fully enclosed and has no exposed frame edge, so this clip is for the MK4, MK4S and MK3.9. Open the ready-made holder in SpeakCAD for free, resize the slots for your tools in the viewer or the chat, then download the STL.
