This stand gives possibility to change filament spools on a bottom CFS without extra movements, just slide on the rails (even in a switched on condition).

And it will not overturn, even if no spools in the top CFS.

All printed parts are assembled in two plates. On the second plate just unnecessary parts, covers and extra crossbar (add 424mm profile) connectors (i'm not using extra crossbar, for me strength is enough).

Other parts to build:

1) V-slot 2020 aluminium profile 360mm - 6pcs

2) V-slot 2020 aluminium profile 424mm - 3pcs

3) M4 8mm screw - 34pcs (i'm using DIN 7380 black color)

4) M4 5mm screw - 18pcs (for rails)

5) M4 t-nut for V2020 - 38pcs

6) M4 5mm heat-set threaded insert - 8pcs

7) Sliding rails 400x45mm - 1pair (i'm using FGV (Formenti & Giovenzana) Comfy 145 SlowMotion 54.5145.C7.40X.00, but you can use almost any 400x45x12mm rails, it all have standard dimensions)

8) Rubber adhesive pads 20*20*2mm - 8pcs (i'm using Space Pi rubber pads after CFS mod)

Assembly using rubber-tipped hammer (i'm using IKEA set). You will hear dull sound when the profile reached the end.

Distance between CFS foot holders must be 200mm, side shift on the top 41mm, on the rails 19mm (all dimensions by the aluminium profile).

Updated for all types of V2020 profiles and added Creality CFS logo and the separate plate with logo (needs two M3 or M4 8mm with t-nuts).
