Simpliest spool holder ever (revised)
attaches to right smooth Z rod (upper part) and holds the spool conveniently, without using any desk space. Print with small amount of infill (I used 7%), and honeycomb pattern. Small notch at the end works as filament guide. Insert 1 or 2 M4 screws to secure it properly. . Note : print with ABS - this works much better, and causes less friction (filament against plastic guide), and spool rotates more freely.
