This should be the first thing you print on the MP Select Mini.

.STL available in the project files. Four M3 nuts and four M3x20 bolts are required.

Just print this out and tape it to the back of your machine.

ASSEMBLY

Because the MP Mini uses a standard thermistor and heater cartridge, you can reuse the stock thermistor and heater cartridge in an e3d hotend. This means a better hotend is a drop-in replacement, without needing any firmware updates or anything.
