- Monoprice MP Select Mini V1
Size: 20mm x 20mm x 10mm
This is an aftermarket part. Instead of the screw and metal tab used with the original, this uses a screw to hold the thermistor wires.
*Some of the last batches of Select Mini V1's had heater blocks that are 16mm x 16mm x 12mm. Please verify which size heater block your printer has.
