Summary

RepRap Electronics Assembly V2

I got tired of my China MK3 Heatbed and switched to an aluminium build plate coated with PEI and a 230V silicone heater. The heater is connected through a solid state relay (SSR) and I realized, that I won't be able to mount my SSR into the old RepRap Electronics Assembly without making changes to it and print the entire bottom frame again.

Thats why I've made a rework, my goal was to make it a bit modular and also sturdier.

The bottom frame now only contains the mounts for an Arduino Mega 2560/RAMPS. The left side is completly empty, but you can fill it with the "modules" of your needs.

The modules look like puzzle pieces, the frame accommodates space for one large module or one small and one medium module.

With these modules you can change the hardware of your 3D printer without the need of printing a complete new frame, just replace the puzzle pieces.

Available modules

Small modules

Raspberry Pi Zero
4x WAGO 221-415 (WAGO 221 Mounts by joochung were integrated into this module)
Blank "design your own" (import this .stl into Tinkercad or the program of your choice and add your own stuff)

Medium modules

SSR
MOSFET-Board
Blank "design your own" (import this .stl into Tinkercad or the program of your choice and add your own stuff)

Large modules

Raspberry Pi 2/3
Blank "design your own" (import this .stl into Tinkercad or the program of your choice and add your own stuff)

The bottom frame still has four small bridges which allow you to zip tie cables onto it.

There are also three versions of the top frame, they're all designed for a 120 mm fan. Use the first version if you want to mount a fan only. The second version contains a fan control (2 potentiometers) and a switch (I use that switch to turn the LEDs on my 3D printer on/off). The third version is a blank "design your own" one, you can add your own stuff.

I've printed it in PETG with 4 horizontal and 4 vertical perimeters, 50 % infill at 0.35 mm layer height. All the parts are easy to print without support structures.

Hope you enjoy it!

Dimensions

150 x 120 x 80 mm (without fan control)
150 x 150 x 80 mm (with fan control)

Materials you'll need

12x M4 nut
4x M4 bolt 20 mm (to connect top and bottom frame)
4x M4 bolt ?? mm (depends on the dimensions of your fan)
4x M4 bolt ?? mm (depends on where you want to mount it)
2x Potentiometer for fan control (optional)
1x Switch (optional)

Just in case you're thinking in imperial units: 1 inch equals 25.4 mm :)
