Dual Budaschnozzle X-carriage & extruders

A X-carriage for the Geetech Dual-head Hotend which uses two budaschnozzles.

Made for Mendel-style horizontal X-axis printers. Has emplacements for three 40mm fans, two on the sides for cooling the buda’s radiators and one in the back for cooling the print.

Also designed for the use of timing belts instead of big and small gear.
