I used Cura 2.5.0 to slice. I printed everything in PLA, the tolerances in this model don't work with ABS. General settings I used: - Nozzle diameter 0.4mm. - Speed 60mm/s for all parts except for ''Long Tube'' and ''Short Tube'' use 30mm/s for those. Make one of every part except for the "Plastic Bearing" you need to of those. Print all parts in the the original orientation. Use support for the part ''Printer mount''. It is also recommended to print the parts: "Printer mount" and "T-piece" with 100% infill. When you use very heavy spools this is NECESSARY. You also need: - M8 threaded rod 145mm long. - 2x M8 nuts to assemble. - If possible I recommend Tread locker (LOCTITE) on the nuts. If you use Cura to slice: Slice the the parts ''Long Tube'' and ''Short Tube'' with a shell thickness of 1.1mm so you don't get infill lines. (this is faster and the quality will be better) You can also use my .gcode files.
