Ramps and Pi Case

thingiverse

Hi. This is my first attempt at making a custom case from scratch to fit my RAMPS 1.6, Raspberry Pi and Mosfets into one compact Case. I also left space for any extras I might want to add later on. I've used a RAMPS 1.4 to work out the placement, and although it hits the 80mm fan, the 1.6 should fit as the onboard mosfets and fuses have a lower profile. I added D-Sub connectors to the side for easy connection of the cables when working on the Case or Printer. The boards are secured with 3M bolts and nuts. There are three key components: Three 9Pin D-sub Connectors: one each for X, Y, and Z axes. Each uses four pins for stepper motors and two for end stops, except for the Z axis, which uses a BL-touch or similar for the end stop. The 15 pin D-sub is for the Hot Bed, using eight pins to carry power from Mosfets to the Heating element and two pins for the thermistor. The 25 pin D-sub is for the Hot End and Extruder, using four pins for the Stepper motor, four for the Hot end, two for each fan, two for the thermistor, five for the BL-Touch, and two for an LED ring. I added a second 25 pin D-sub for any AUX items that may be added, including an enclosure LED or a filament run out sensor. For air circulation, I've added three fans: two 40mm fans at one end and an 80mm fan in the lid. This should provide enough airflow to keep everything cool. This design was created using Fusion 360, and I have included the file for your reference.
