Threaded e3d hotend adapter for leapfrog printer
Part that replaces the original heatsink and allows to adapt an e3d type hotend with thread, similar to those used for the duet smart effector.
Adapter to tilt the printing fan so that it blows towards the nozzle area. I will try to design a fan duct when I have some time.
To connect the bltouch I have taken advantage of the thermistor and fuser connections of extruder number 2 of the original electronic board. The two GNDs can be paired on a single pin.
