Ramps case for Pi4

thingiverse

This thing is perfect for an Arduino Mega256 with a RAMPS1.4 board that has TMC2130 stepper drivers installed. It features mountings and openings for a RasPi4 running Octoprint. While building my Prusa-like printer, I was struggling to find an enclosure that fit all my needs. I came across several really nice enclosures, but none could accommodate the extra height required for the TMC2130 stepper connections. I also wanted to include a RasPi, and since I had just bought a Pi4 to play with, I decided to add it. As a side note, the Pi4 is fantastic for Octopi! Here's the result: A Ramps enclosure that can fit a Mega256, RAMPS, TMC2130s, and a RasPi4. I tried to make all slots accessible, but I'm not entirely happy with the need to loop back the Mega-RasPi USB cable. This is the only way I could think of to make it both compact and allow external access for programming or control. It's not the prettiest solution, but I managed to find some 12-inch USB cables to reduce the length. Other USB sockets and Ethernet ports can be accessed from the bottom for cameras and other peripherals. The RasPi4 HDMI connector is on the front, and the RasPi SD card slot is on the right side. The Ramps SD card slot is located on the left side. The enclosure features two fans: a 50x20mm fan on the right side to cool the stepper controllers and a 40x10mm fan on the bottom to cool the RasPi. You may want or need to change the sizes of these fans based on your specific requirements. The SCAD file also includes some other custom models that I used to build my Prusa-like printer, but they might not be useful for anyone else. I'm not sure if this enclosure will be helpful to others, but it's here nonetheless.
