About this 3D model

I've remixed the previous model in order to enhance it. Now M3 heat inserts are used, M5 screws are used for connecting the levier to the mechanism, a new design of base was created. The knob now is fixed to the levier using a M5 screw. I've used an attiny85 that can be fixed directly under spring mechanism (the code is provided in the zip) Parts required: 1x M4 x 50mm 3x M5 x 35mm 2x M5 x 20mm 1x M5 x 40mm 8 x M4 x 35 or 40mm 2x microswitch 1x Attiny85 1x extruder spring Wiring: one wire from ground to the both microswitch pin 0 to the first microswitch pin 2 to the other microswitch 13/1/2024 - pulley, spring base mount and spring holder updated - a full length spring can be used. For the code get the .txt attached and change the extension to *.rar and unzip.
