Summary

A heavily reworked AM8 electronics case, designed to fit a RAMPS 1.4 board, two MOSFETs and a 120mm fan.

Features:

  • Mountable on the AM8 frame using 5 regular M5*10 screws.
  • Houses a RAMPS 1.4 board, uses 3 mounting holes.
  • High enough to house a full graphics display adapter and TMC stepper drivers.
  • Houses two MOSFETs, one for the hotbed, one for the hot end.
  • The lid allows you to mount a 120mm fan. The X motor needs to be rotated on the other side of the X holder to make room for it.

WARNING: The fan needs to have a bit of a dent to allow access to the lid screw hole. Check the 3rd picture. If your fan doesn't have a dent, you will have to grind off a bit of material from it. I plan fixing this in a future version.

Assembly:

  1. Mount the case on the AM8 first using 5 regular M5*10 screws.
  2. Mount the Arduino Mega 2560 into the case. Use 3 M3*10 screws and 3 printable spacers included in this thing.
  3. Mount the RAMPS 1.4 board and all modules you want onto the Arduino afterwards.
  4. Mount the two MOSFETs using a total of 8 screws usually used for screwing in optical drives in a PC. M3 should work as well.
  5. Install the 120mm fan on the lid. Use 4 M4*35 screws with countersunk heads. Please refer to the fan warning above.
  6. Install the lid on the case using a single M3 nut inserted into the case part and an M3*10 screw on the lid.

There is still room for improvements. If you notice anything that you would improve, or if you have a suggestion, please let me know!

As usual, I am including the Blender source file in case you want to edit it.

Good job ! I have a suggestion, as you propose, Can you draw an addon enclosure for lcd 12864 in front of the case, I'm interest by having a complete electronic module outside the Anet not screwed on the printer, I'll be able to have all the electronic outside the box containing the printer. So the box and the enclosure put aside the printer.

I'll try but not sure I can do it alone...

Regards Eric

For that kind of thing (sounds like something completely else), there should already be plenty of different designs already available. It would be a completely different upload than this anyway. :)

thanks for your reply
