📦 Prusa Tool Box Inserts – Secure Sorter
🧰 Keep your Prusa accessories organized and secure!
These two custom inserts are made for the Prusa Tool Box V2, compatible with MK4S, MK4, XL, MK3.9, MK3.5, MK3, Mini+, and Mini printers.
They solve a simple but annoying issue: when the box is turned upside down, all the small screws, springs, or nozzles start flying around.
💡 With these inserts, that won’t happen anymore.
They fit perfectly below the original trays – which now act as lids – so your small parts stay exactly where you left them.
🔩 Perfect for storing:
Spare screws and nuts from your Prusa printer
Nozzles, bits, and other small hardware
Clips, zip ties, or mini tools
🖨 Print Settings:
🧵 Material: PETG or PLA
📏 Walls: 2
⬆⬇ Top/Bottom Layers: 3
🧩 Infill: 15–20%
🌡 No supports needed
✅ Tips:
Use PETG for higher durability if you move the box often
PLA works fine for stationary storage
The fit is snug – make sure your printer’s dimensional accuracy is dialed in
