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

UPDATE: Considering recent comments, I've decided to redesign my previous creation to increase clearance between the extruder and the spool holder. The updated version can be found at https://www.thingiverse.com/thing:2904072. I'm a big fan of the original design by IsmaelPR1, which can be seen here: https://www.thingiverse.com/thing:1768975. It must have taken him a lot of time to come up with this design. The integrated filament guide is really great. I printed the original design and found that it takes a long time to print the bolts as well as the spool holder with the built-in filament guide. This is because it's printing predominantly in the Z-direction, which slows down the printing process due to cooling issues. Additionally, the results aren't the strongest either. Since I also 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 filter. A few months ago, I designed some improvements and left them aside. Recently, I was able to print the updated design and made some further changes. Now, I'm sharing these updates: This remix has a separate filament guide that prints more in the X/Y direction (since it's lying flat on the bed) and therefore prints faster and is much stronger. The filament guide is attached to the right spool holder support element using an M3 bolt (you can use a spare bolt from the Prusa spare parts kit) or by gluing it (if printed in ABS, you can glue it 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 so that you can just insert the filament through the cut. In addition, the original bolts had threading throughout their entire length, which is not necessary. 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've added some newly designed nuts as well just for aesthetics. Furthermore, I ran some cables on the backside of the top frame for my lights and made some recesses in the main spool support elements so that cables can be guided between these holders and the frame. For the rest, no changes have been made, so you'll need to grab the other components (spool rollers) from the original post at https://www.thingiverse.com/thing:1768975. Kudos to IsmaelPR1 for designing and sharing this great design. Update: I've also quickly drafted a "spool lock" to keep very light (sample) spools in place on the Easy Spool Holder.
