3D printer folks, this is a handy pack of spare heater blocks.

You get five of them, made from aluminum alloy with a sandblasted, oxidized finish.

They're the common V6 style, measuring 20mm x 16mm x 12mm.

They have an M6 threaded hole for the heat break, a 6mm hole for the heater cartridge, and an M3 hole for the thermistor or thermocouple.

They're compatible with MK7, MK8, and similar MakerBot hotend setups.

If your current block is gunked up with filament, stripped, or you just want some spares for different nozzle setups, this pack is great value.

Keep them clean and ready for your next hotend rebuild or maintenance session.
