Voron Decontaminator using Bambu Nozzle Wiper

Allows using BambuLabs Wiper with Voron Decontaminator buckets.

Features:

• wall guard for easy bucket mounting even with imprecise hand movements
• mount holes in positions where Voron Decontaminator bucket mod expects them (for magnets catching mount screws)

Printed from ABS, with Voron recommended print settings. 2x M3x8 SHCS + 2x M3 T-nuts for mounting to 2020 extrusion. BambuLabs Nozzle Wiper mounted using self taping screw that comes with wiper.

Fusion 360 source CAD file attached.

Idea from https://www.printables.com/model/580157-bambulab-nozzle-wiper-for-vorons-bucket-purge-mod but redesigned from scratch.

Currently experimenting with such macro (to give you an idea; depends on various other macros), run before quad gantry leveling. Note, my bed is moved slightly to the front, so instead of 350mm in Y axis I have 355mm available.

If you have improvements please comment.
