This bottom block is used together with the main block and the clamp.
It is used to clamp the bottom bearing and close it all up.
Please be aware that I don't have an Ultimaker to test, but it has been developed with a customer who does. It is still a little bit work in progress.
This can only be used with:
Main block
Hot end Clamp
The Nimble Extruder
With an installed weight of less than 27 grams on your carriage/effector the Zesty Nimble is smallest and lightest extruder you can buy, it has ample torque and can be mounted in multiple orientations.
The Nimble is available from
Zesty Technology.
