Are you ready for the next heatwave? 🌡️

One of our most popular 3D prints right now is the dual-hose conversion kit for the Blyss A018I-12CH portable air conditioner.
This simple printed adapter lets you attach a second (intake) hose to your unit — drawing exhaust air from outside instead of from inside your home.

Why does that matter? Single-hose units create negative pressure in the room, quietly pulling warm air back in through gaps, doors and windows. That means your AC works harder for less. A dual-hose setup helps it run more efficiently and cool more effectively.

🤝 The people we trust

At Hark Tech we run every repair and every 3D print in-house. But there are two jobs we happily hand to specialists we know and trust, and we have pulled them together on our Partners page.

🔧 CEEQ Design, a Basingstoke engineering studio. Got an idea, a sketch, or a broken part with no file? They turn it into a proper CAD model and we print it.

🌿 Soloré Creations, ready-made 3D-printed gifts, lamps and garden décor from around £6. No CAD, no uploads, just pick a finished piece and order. They even run a bespoke clothing range.

So whether you need something designed from scratch, printed, or ready to gift, there is now a clear path for it.
