This set fits the 3DFactories spools. The base is just clipped into the original basis of the printer on the right side of the Cubex Duo, if you have a Trio you have to remove the third support of the Cubex, if you have Cubex with single extruder you have to move your support form the left to the right side of the printer because these spool are much more larger and only on the right side there is enough room. For the spool I use a metallic axle 8mm/102mm but if you want you can print one. Use Kisslicer with Cubeitmod to print with external spool without any original cartridges inserted. Kisslicer+Cubeitmod strongly improves the quality of your printed parts. Subscribe to google group "Kisslicer Refugee Camp" and you'l find all the information required.
