A modular plate that allows you to mount smaller things more easily and with less waste when your setup changes. 

Compatible with 180x180x180 printers!

The idea is to have a Rackfinity 1U insert that has an array of countersunk M3 holes through it. This allows you to print small adapters for stuff like switches, Raspberry Pis and other things. Next, you can use countersunk M3 screws, washers and nuts to screw the modules onto the plate in any orientation you want. And if you ever want to replace parts or rearrange them then you don't need to re-print an entire 1U insert, just if needed, print a new plate for holding whatever you want to add.

Parts needed for assembly:
- 6x M4x20mm screws (to screw in the front and back plates).
- 6x M4 nuts (for the above screws, heat- or friction-fit into the bulk parts).
- 4x M4x20-25mm screws (to screw the back and front bulk pieces together).
- 4x M4 nuts (for the above screws, heat- or friction-fit into the bulk parts).
- 4x M5x10mm screws (to screw into the rack).
- 4x M5 nuts (to be inserted into the rack where this thing will sit).
- Nx M3xNmm countersunk screws to be used for your modules (depends on the modules).
- Nx M3 nuts and washers for the above as needed.

(The included Raspberry Pi holders require 4x M2.5x6mm screws, 4x M3x6mm countersunk screws and 4x M3 nuts).
(The included ys25-0402 switch holders requires, at least 2x M3x10mm countersunk screws and at least 2x M3 nuts with washers).

The pattern has the following spacing:
10mm between 3.5mm holes on a grid. Each row of holes had a bump on it so that modules are aligned. You can see it in more details in the included step file or the pictures with dimensions.
