colorfabb 2.2Kg Spool Holder

thingiverse

I am extremely satisfied with this simple design after using it daily for over a year now. Indeed, Colorfabb's products are of great quality, but I prefer to use their bigger 2.2 Kg spool instead of the standard small 750g spool (which can be found at http://colorfabb.com/standard-white). The larger spool does not fit in the default Ultimaker spool holder, so I decided to use my own custom-made holder with bearings. When designing mine, I took inspiration from other ideas on Google Images last year. One idea that likely influenced me was a design for small spools found at https://www.thingiverse.com/thing:486027. You will need 4 bearings (16x5x8mm) and simple screws and nuts to assemble this holder. I used some spare parts lying around on my desk. I have posted the original FreeCAD file, so feel free to use it as you see fit. It might be a good idea to mount horizontal bars instead of just 4 bearings to accommodate spools of different sizes. However, I didn't need to do that. Here are my print settings: 0.150mm layer thickness, 5 mm brim width, and 0.8mm shell thickness. I also used a moderate infill percentage of 10-15%.
