Domo My Blender keep on mechanical switch

Do you own a Domo My Blender (https://www.domo-elektro.be/en/kitchen/mixer-blender/my-blender-original-green)?
Its a great small blender, I use it for smoothies each morning.
Annoying thing is that you have to keep on pressing the button for it to keep ... blending :-)

So I designed this small mechanical pusher.

Requirements

• print the housing.stl (no support required)
• print the pin.stl (support IS required)
• print the knob.stl (nu support required)
• 1 x M4 screw 20mm
• 1 x M4 nutsert (to push in the pin so you can screw the knob in it)

Assembly

• put the M4 nutsert in the pin, I used my soldering iron to let it sink in the plastic
• push the housing in the bottom of the blender (should fit snuggly)
• push in the pin between blender and housing
• take the M4 screw and attached the knob to the pin
