A nozzle cleaner and purge tray mount for Snapmaker 2.0 machines. It was specifically designed for the A250 where both screw holes can be affixed to the underside of the bed framework with two screws.

Two STLs are included for the front left and right sides of the bed framework. Rotate the model 180 degrees along the X-Axis (my bad). Prints without supports. BOM at bottom of description.

You will need to make adjustments to your starting GCODE to allow for the machine to position itself over the purge tray during purge, and brush itself against the wire brush with a hot nozzle. I've documented mine below as a reference:

NOTE: If you print with a high bed temperature (~80C+), due to the contact with the print bed, you should print the model with a material that has a high glass transition temperature so as to avoid warping the model over time.

BOM:

• 2x M4x6 screws
• 1x Mini wire brush (or use a standard wire brush and saw through it at the head)

I used the following wire brush: https://www.aliexpress.com/item/1005005814644069.html?spm=a2g0o.order_list.order_list_main.124.1a311802jC1it1
