Design Concept:
This model is an Ender 5 Max Spool Holder Cover which slides over the stock Ender 5 Max's Spool Holder bracket and screwed in place to prevent a potential Spool Jam that occurs with certain Filament Spools that have large cutout holes such as Sunlu, Bambu Lab, eSun, etc... These types of Spools have cutouts that allow you to see how much filament you have left and also it causes less plastic to be used in the molding of these plastic filament spools, and because of these large cutouts, they have a potential that they can get caught by the Ender 5 Max's screws that hold the spool holder in place to the printer frame (see picture 2 for example). When the spool is caught like this, the filament spool will get caught in place preventing any further filament to enter into the extruder and into the hotend which eventually kills the print, especially on long prints. This cover is a elegant mod and is functionally a needed mod to the Ender 5 Max as well as it can be an aesthetically pleasing mod for those who want to add another colorful accent to their printer as well as a needed modification to their Ender 5 Max.

This issue isn't Creality's design fault as the screws are rounded which helps a lot, but these large plastic cutout spools are mostly the issue as not many filament brands use plastic spools nor do they have such large cutouts on the spools to see how much filament is left, at least that's my believe, it's more a freak occurrence that can happen.

Print Settings:

I printed mine with 100% infill, Organic Tree Strong, and printed it on the side vertically (see picture 3), and with PETG. You can basically print this with any material you want and any infill setting you want but I strongly recommend to print this only vertically up with the screw holes for the bracket being at the top. The reason why I say to print this with 100% infill is for the strength as this slides pretty tight but not too tight to the metal bracket and if you print with anything less than 100% infill you may risk snapping the cover.

Assembly:

1. Once the cover is printed, unscrew the spool holder bracket from the printer frame.

2. Unscrew the Spool holder from the Metal Bracket.

3. Slide the cover with the opening on the right to the left of the metal bracket, (it should look like picture 4).

4. Screw the Spool holder to the large hole of the combined Metal Bracket and the Spool Cover (it should look like picture 5).

5. Then screw the entire thing back into place on the Printer frame (I recommend that you level it, see picture 5, but not needed).
