Luke's Lab Chube Compact Hotend — with Heater & PT1000

Details

Pre-order: Luke's Laboratory can't give a firm ship date for the Chube Compact yet. Order now to reserve yours from the first batch — we'll keep you updated as soon as we know more, and it ships from the Netherlands as soon as it lands, with no import duties or courier fees on your side.

The Chube Compact is Luke's Laboratory's hotend for DIY toolheads: everything that made the original Chube a high-flow, high-temperature hotend, packed into a Dragon-sized body. A 33 mm meltzone, a Chalice titanium heatbreak, standard V6 nozzles, and the Dragon 4 × 16 mm M3 bolt circle, so it drops into toolheads that already have a Dragon mount. No meltzone adapter needed.

It comes fully assembled with the heater and PT1000 fitted and greased — bolt it in, wire it up, print. The stainless heatshield keeps part-cooling air off the block, so it holds temperature even without the sock.

Nozzle: pick No nozzle if you already have V6 nozzles, or add a 0.4 mm Luke's Lab Two Step nozzle — nickel-plated copper for everyday filament, coated hardened steel for carbon- and glass-filled. Other sizes are in the shop as separate nozzles.
