Alu-Dual Hot End & Cooling Block Upgrade Spacers
Alu-Dual Hot End & Cooling Block Upgrade Spacers.
These are the spacers you need to print the the Replicator 2X BEFORE you start the upgrade. I printed 2-off each - the 2.4mm spacer work well with the 3 in 1 extruder upgrades.
For a stock setup Carls suggests using a 3.5mm spacer.
The main reason for the upgrade was to allow PLA to be used and printed reliably.
The upgrade was from RAFFLE, Carls shop.
