Magnetic Direct Drive Extruder 3D print model

All of the design is modular. Two base parts connect each other with 6 pieces of 10mmx5mm (Diameter x thickness) and 6 pieces of 10mmx3mm Neodymium magnets. 5mm thickness ones are pasted to Part1 and, 3mm thickness ones are pasted to part2. Using 6 magnets for both sides is strong enough, even so, you can try to use 4 magnets for both sides. Probably it will be enough too.The desing's adventages:

You can print all of this design's parts without support by positioning correctly.

You can use different extruder designs without untying the belt.

You can control and fix any trouble on nozzle easily.

You can print TPU flexible filament

Reducing retraction distance. My retraction distance was 5mm when i use bowden extruder but now it reduced to until 1mm.

All design is detachable even the layer fan duct and you can change the design for your 3d printer. For example i use sn04-n indactive sensor for auto bed leveling but if you use a different sensor or don't use any sensors, you can change the design easily.
