I was unsatisfied with the Filament Buffers here on Thingiverse because they seemed to be bulky, and too massive, so i designed my own with the inspiration of the Buffer of https://www.thingiverse.com/thing:4013669. I re-designed the whole Buffer myself, so there are no compatible files between this and https://www.thingiverse.com/thing:4013669

#The Key features are:

• it has hinges so you can bolt them to a surface and choose the appropriate filament without needing to hassle around because of limited space
• It is compact, only the most necessary parts needs to be printed, the Bottom of the case is open and free to pushed out. That saves time to print.
• all Files can be printed without any support and are already oriented in that way.
• All Parts for one Filament Buffer can fit on one Buildplate (of a Prusa Mk3) so you don't need to wait for the rest of the parts to complete in order to have one Filament Buffer up and working.

I have embedded the Case in basically 2 variants:

• one without any cutouts and markers
• five with cutout and embossed numbers from 1-5

Use them as you want.

Needed additional Hardware

• Screws to bolt the Anchors to a Plate (one for each Anchor)
• 608 Bearing (one per Slider)

Optional but recommended additional Hardware

• M5 inserts (used the M5 Inserts from Ruthex) - 2 for each Slider
• M5 Tube Fitting sockets (PC4-M5 in my case) - 2 for each Slider

Have fun.
