Last crawled date: 4 years, 7 months ago

This is a purge bucket attachment for the Geeetech A10t printer, for the purge blob method of color printing.
The x-axis cover plate allows the nozzle to move off the build plate to reach the bucket.
Put silicone in the arm (the white in the picture) for the nozzle to wipe on.
