Best upgrade for the price

Cheap and effective. If you are running a MakerBot clone or original with an MK8 head, this is a must-have spare part to keep on hand.

Good quality, minor installation tip

The material feels very durable. Just make sure to tighten the set screws gradually to avoid stripping the threads. Works great with PLA and ABS.

Excellent thermal conductivity

Notices a faster heat-up time compared to my stock part. The aluminum quality seems superior. Very happy with this purchase for my garment prototype printer.

Perfect fit for my upgraded extruder

This aluminum block fits my MK8 setup perfectly. The threading is precise, and it heats up evenly without any hot spots. Great replacement part.

Solved my clogging issues

My old block was warped causing inconsistent extrusion. This new one resolved the issue immediately. Highly recommend for anyone troubleshooting flow problems.

Solid component

Does exactly what it is supposed to do. The machining is clean. I deducted one star only because the packaging was a bit loose, but the part itself is flawless.
