At first, i did not want to make an instructable on how to stack a couple of 3D printers on a shelf, but the final result turned out so nice, i decided to share it with the community.
Step 1: The Wall Color
The chosen colour for the farm background is black. You will need some black interior paint and a paint brush. The background colour will help highlight the 3D Printers.
Step 2: The Shelf
You will need a sturdy shelf to support the printers. I chose a PVC shelf that supports 70KG per shelf. The shelf i chose is not very sturdy, for that reason i used some extra support ( pictures ). This shelf can stack up to 8 printers (Prusa i3).
Step 3: Lighting Up the Printers
The shelf's naturally create shade onto the printers, so for that reason LED strips are glued on the bottom of each shelf in order to illuminate the 3D Printer's build space.
Step 4: The 3D Printers and Spool-holders
Now that the shelf's are well fixated on the wall, you can position your printers in place. Make sure to position the printers in a way you can change the filament effortlessly, and perform maintenance routines with ease of access.
The power supply are all stacked one on top of each other at this point, but i intend to position them in the lower shelf in the future.
Step 5: The Final Result
Our 3D printing farm is fairly small, but it compensates with its good look's =)
