Replacement Parts

Nozzle Assembly

  • Our printer has a Budaschnozzle 1.1 with 0.35 nozzle
  • The Nozzle itself is a 13mm AF hex with an M10 thread.

Replacement Nozzles


Heater Element

The heater element is heated by a 4.7 Ohm Wire Wound Glass Enamelled Resistor. Unfortunately they seem to fail fairly regularly

It is a 6W device. The part is a Vishay or Sfernice RB57 6x22 4R7 Enamelled Resistor.

Vishay 4.7Ω Wire Wound Resistor 7W ±5% RWM06224R70JA15E1
Mfr. Part No. RWM06224R70JA15E1
RS Part Number 485-2603 ~£1.40 each
