Ender 3 (Pro) - Raspberry Pi Model B+ Case [Rear mounted] (MOSfet LEDs, & Relay)

thingiverse

UPDATE (23 Jun 19): I've printed a lot of benchy3D boats, and I have finally found what I believe are the best simplify3d settings. So I uploaded it to share - keep in mind my G-code Scripts are an Ender 3 Pro running a BLtouch and vanilla Marlin. UPDATE (29 May 19): I changed the DuPont 4-pin female connection for expansion (Filament sensor, etc...) to an 8-pin DuPont connector so I can add an LED ring around my camera and a filament sensor to my printer in the future. UPDATE (11 May 19): My kid flipped the power switch on the printer about halfway through printing my 09may19 update, so I decided to make one more change before I print it again. I changed the DuPont 4-pin connector hole to house an 8-pin connector in case I want to add anything else controlled by the pie later on. Also added an arrow to the DuPont access hole to indicate where pin 1 is. UPDATE (09 May 19): - The box no longer requires supports to print; I included the supports. - I uploaded a mod list of all the mods my printer has installed. - My Simplify 3D profile. - My configuration.h and configuration_adv.h for Marlin vanilla bugfix 1.1.9. - Be aware that my Simplify 3D profile and configuration files are for an Ender 3 with a BLtouch installed. Details: - I really liked Marvinda's "Ender 3 (Pro) - Raspberry Pi Model B+ Case for OctoPrint with Relay Control." https://www.thingiverse.com/thing:3384729 - I wanted to do the same thing but mount it in the rear of the Ender3 underneath the power supply. I also wanted it to be very quiet, and control a 5V LED light strip via MOSfet module and an IR ring for a pi cam. - Print out the included Y-Axis Endstop before installing the OctoPrint server box or it won't fit. If you want a Pi Camera, I recommend this mount: - https://www.thingiverse.com/thing:3426025 - I remixed it to use M3 screws here: https://www.thingiverse.com/thing:3593230 - If you want LEDs, I recommend this gantry mount: https://www.thingiverse.com/thing:3367976 Required Hardware: - 11x - 10mm M3 screws - 4x - 16mm M3 screws for the fan (15mm will work too) - 15x - M3 nuts Parts List: - 1x - SLA-05VDC-SL-C Relay w/ optocoupler isolation: https://tinyurl.com/yy6h7c9u - 1m - 5v Led Strip: https://tinyurl.com/yxdojqn8 - I only used 1 foot, but I was glad I had extra for how many times I messed up soldering it. - 1x - LM2596 DC-DC Adjustable Step Down 3.2-46V to 1.25-35V: https://tinyurl.com/yynlo9u5 - Be sure to adjust it to 5v with the setscrew and multimeter before you power anything from it. - 1x - 5Megapixel 1080p Sensor OV5647 Mini Camera Module: https://tinyurl.com/y2kblxbg - 1m - FFC 15pin Ribbon Cable (For Pi Cam): https://tinyurl.com/y53dxjx9 - 1x - Dupont wires Male to Female, Female to Female: https://tinyurl.com/y6krynw4 - I used this kit: https://tinyurl.com/y2o7rm8n - 2ft - 14 GAUGE WIRE RED & BLACK: https://tinyurl.com/yykn87pt - 10ft - 22 GAUGE WIRE RED & BLACK: https://tinyurl.com/yx9mhge3 - 1x - XT60 Connector Pair (Male & Female): https://tinyurl.com/yydnug8m The "config.yaml.txt" file includes all the custom code and commands I have added to the controls tab, including the LED off and LED on Commands. Just ssh into your raspberry pi and edit the config.yaml: $ sudo nano ./~octoprint/config.yaml
