Build the heated block assembly by fastening together the following components.

Copper/Titanium Heatbreak

Aluminium Heater Block

Stainless Steel Spacer - An oversight with the initial batch of kits (pre-2024) meant that these spacers were too short - longer 19mm spacers have now been shipped separately to everyone.

Nozzle - This can be of your choosing: Brass/Stainless Steel/Hardened Steel

We recommend using PTFE tape to wrap the threads (3-4 turns) to prevent any leaking. PTFE tape was included with the set of hardware sent out later to pre-2024 customers.

Tighten as firmly as you can - we will also hot tighten later.

Repeat this assembly for the number of print heads you're building.
