Step 1
The original dial knob is pressed into of the gear dial knob (roue dentée.stl) all the way to the shoulder. Remove the original know from the grinder to do this, the forces needer are quite important, I used a hammer an a piece of wood to protect the original dial knob.
The cover (Couvercle.stl) is placed later on top of the knob after you setup you grinder to the "0" position.Step 2
The worm gear (vis sans fin.stl) is secured inside the housing to the dial knob (Bouton.stl) with a headless M3x12 mm screw.You will habe to thread the M3 across both parts prior to lock the screw.
Step 3
2 M4 threads are required on the side of the grinder to attach the housing (Carter.stl). A drill guide (Posage.stl) will help to position the initial 2.5mm holes. The drill guide is placed on the upper corner flushed with the front face of the grinder. I did place 2 M4 helicoil thread inserts right away to make sure I have a good fixation of the housing. 2 M4x10 mm screws are needed. You may also have to file away some of the side guides from grinder cover not to interfere with the M4 screws.
