A purpose-built storage solution for your Bambu H2D hotends, designed to fit seamlessly into your Gridfinity workspace. Holds 2 hotends across × 3 deep (6 total slots) per unit — and units stack vertically so you can build the storage as tall as your hotend collection demands without taking up more bench space.

🧱 Stackable Design

Each unit interlocks securely with the one beneath it, so you can scale your storage upward instead of outward:

• Stack as many tiers as you need — 6 hotends per layer, grows with your collection
• Stable, aligned stacking — units register positively to each other so the tower doesn't shift or slide
• Still fully Gridfinity — the base unit drops into your standard Gridfinity baseplate, and the whole stack stays anchored
• Pull the top unit off any time you need fewer slots, or add another when you expand

(This is the corrected, genuinely stackable revision — the previous version was not stackable in practice. This one is.)

✏️ Fully Customizable Text in Bambu Studio

Each hotend slot has editable labels you can change in seconds — no CAD software needed.

How to edit:

1. Open the file in Bambu Studio
2. Go to Global Edit Text
3. Type whatever you want for each label (filament type, nozzle size, color, brand — your call)
4. Slice and print

Label your slots however makes sense for your workflow: PLA / PETG / ABS / TPU / PA-CF, or by nozzle diameter (0.2 / 0.4 / 0.6 / 0.8), or by hardened vs. standard — whatever helps you grab the right one fast.

🎯 Why Dedicated Hotends Matter

If you print across multiple filament types, matching your hotend to your material isn't optional — it's the difference between consistent prints and constant troubleshooting.

• Abrasive filaments (carbon fiber, glow-in-the-dark, glass fiber) chew up standard brass nozzles and ruin print quality on subsequent runs of non-abrasive material.
• High-temp filaments (PA, PC, PPS-CF) can leave residue that contaminates lower-temp prints.
• Soft filaments (TPU) print best with a clean, dedicated flow path.

Cross-contamination between materials causes layer adhesion issues, color bleed, clogging, and inconsistent extrusion. A dedicated hotend per material family eliminates 90% of these headaches.

🔄 Built for Fast Swaps

Bambu's tool-free hotend swap is one of the H2D's best features — but it only saves time if you know exactly where your hotends are and what's in each one. This storage unit:

• Keeps every hotend upright, organized, and labeled
• Lets you grab the right one in seconds when changing filament
• Protects the silicone socks and heater blocks from getting knocked around in a drawer
• Sits on your bench in Gridfinity formation — and now stacks upward — right where you need it

📐 Specs

• Footprint: 2×3 Gridfinity (standard 42mm grid)
• Capacity: 4 hotends per unit, unlimited via stacking
• Stackable: Yes — units interlock and register to each other
• Compatible with: Bambu H2D hotends

🖨️ Print Settings

• Recommended material: PLA or PETG
• Supports: Not required
• Infill: 15% is plenty (consider 20%+ if you plan to stack several tiers, for a sturdier base)
• No special settings needed

Stop hunting for the right hotend mid-project. Print it, label it, stack it as high as you need — and never mismatch a nozzle to filament again.
