AMS like front loading spool holder

Since my H2D is sitting next to other printers, using the side spool holder was really a pain. I therefore designed this spool holder that sits on the top of the printer where you can load the filament from the front, as you do with the AMS, which has proven to be a much more convenient solution.The cover is optional, it is not designed to be air tightThe spool holder sits on 4 rubber fits (those on the picture are found on Amazon) so it doesn't slide when the printer shakesThe rollers use 4 x F695-2RS flanged ball bearings and 4 x M5 x 20 screws (preferrably button heads)You can attach a M6 PTFE tube coupler on the rear or alternatively route the PTFE tube directly to the inlet on the printer (simplest solution for a smooth loading of the filament)Tips :If you use a M6 PTFE coupler the required PTFE length is around 30 cmIf you use a PTFE coupler, it's a good idea to use a drill bit to chamfer the inlet of the filament on the threaded side of the coupler. This will prevent you
