Ultimaker - The Ultimaker 2
I modified the design to use 608 RS2 bearings and M8 hardware since I had those already. Thanks for providing the STEP files that allowed me to do so!
The base looked a little to weak for my taste. I used the one from https://www.youmagine.com/designs/low-friction-um2-spoolholder which fitted nicely as it also uses M8 hardware.
