This model remix different great designs

• Mechanism from KlickSwipe
• Mount by mixing voron-v01-nozzle-brush and KlickSwipe
• Docker by mixing ZeroClick and v0-servo-arm-for-silicone-brush

Description

I want to use ZeroClick while keeping my current nozzle cleaner setup, at the same time not sacrificing print area. So I modify based on KlickSwipe design, and replacing the klicky dock to my own remix.

BOM

• MG90s Servo
• 2 x M3 nut
• 5 x BHCS M3x8mm
• 4 x Threaded Insert M3x5x4
• 2 x BHSC M3x6
• 4mm OD PTFE Tube 49mm total 14mm x 3, 7mm x 1 cutting jig included
  • please refer to KlickSwipe for the jig and how to preparing the PTFE tube
• 6mm x 3mm magnets (voron standard size)
• Silicon brush
  • cut it to the right size
• M2x8mm Self Tapping Screw (Optional)
  • I do not use it, but keeping the hole on the docker model

Adjustment

I have added few layer of blue taps as the probe was sticking to the docker too well that i am not able to attach it.

I have also adjust some of the parts so that it fit my case, if it is too loose for you, please check out the original model from KlickSwipe.

Assembly
