SummaryThis pendulum and clamp combination allows you to mount your Ubis hot ends to the Dondolo extruder. No other parts need to be changed to accommodate this modification. Make sure you re-zero your Z-axis so you don't crash your print head into the bed after changing extruders!InstructionsDo not over-tighten the clamp screws. There will be a gap between the clamp and the pendulum after the hot ends are secured. Too tight will cause the pendulum print to split at the nuts.
