Easy Spool Holder slightly tweaked (Prusa MK2 / MK2S / MK2.5)

It must have cost him a significant amount of time to come up with this design. The integrated filament guide is also a fantastic feature. I printed the original design and found that it takes quite some time to print the bolts as well as the spool holder with the integrated filament guide, primarily because it prints predominantly in the Z-direction and slows down due to cooling. Additionally, the results are not very strong either. Since I use filament filters on each roll of filament, I had to cut the filament guide so that I can insert the filament without removing the filament filter. As a result, several months ago I designed some improvements, left it alone for a while and recently was able to print it and made some further improvements. Now I am sharing these with everyone: This remix has a separate filament guide which prints more in the X/Y direction (since it's lying on the bed) and hence prints faster and is much stronger. The filament guide is attached to the right spool holder support element by an M3 bolt (you can use a spare bolt from the Prusa spare parts kit) or by gluing it (if printed in ABS it can be glued with Acetone). I added two 45-degree recesses in the filament guide; you can either choose to leave the filament guide in one piece, or quickly make a small cut with a saw or sharp knife such that you can just insert the filament through the saw cut. In addition, the original bolts had threading over the entire length which is not needed either. Therefore I made a rod with only threading at both ends of the rods and also these rods can be printed horizontally lying on the bed and as a result can be printed faster and are stronger. I added some newly designed nuts as well just for the looks. Furthermore, I ran some cables on the backside of the top of the frame for my lights and made some recesses in the main spool support elements, such that cables can be guided between these holders and the frame. Kudos to IsmaelPR1 for designing and sharing this great design.
