This is a bracket I designed to replace the wiper that comes standard on a Lulzbot Mini 1. It works in conjunction with a silicon wiper for a Bambu A1 that can be easily sourced for a few dollars on Amazon or Bambu's website. It may be compatible with newer Mini models but I have no way of testing this. This original file has a slight defect in the screw spacing that I plan on correcting but can be mitigated by applying a bit of lateral pressure when screwing it down. The silicon wiper goes on the right hand side of the wiper, the same side that the pointy end of the wiper is on. I provided a file for the receptacle that you can print to go underneath the print bed for catching the purge cycle I included in the G-code below.

REQUIRED G-CODE

To make this work you will need to replace the wipe sequence with this purge and wipe sequence in your slicers machine start G-code. You may need to adjust the Z height depending on the Z offset of your printer. I also recommend adding an adaptive purge to your start G-code here, https://www.printables.com/model/1035759-adaptive-purge-for-any-3d-printer-using-slicer-var
