Modified with several changes. Mix and match to suit your needs - eg. use the servo arm for cheap 9g servos, use the OG gantry mount to mount underneath 2020 extrusion

Gantry mount modified to be able to be attached to upright 2020 extrusion.
Changed the bucket geometry to have a shorted bucket and integrated nozzle wipe using Centuri Carbon wipes adapted from watching The Rat's (https://github.com/charliemayall) solution
Added a magnetic waste catcher
Added a servo arm for more powerful 7kg servos (https://www.amazon.com.au/Changor-Waterproof-Excellent-Performance-1-2x0-5x1-2in/dp/B0GWZKLYHL) - It's a tight fit into the base but that also means it doesn't need any screws or glue to keep it in.

None of these mods affect the other so you can mix and match the parts to suit. The base is needed for the waste catcher but the gantry mount and bucket can be added independently to the blob chute

I also added aluminium tape to the sides of the bucket and the top of the slider.

.step so you can adjust to your needs
