3D-Printer Controller Box

thingiverse

This is a "simple" control-box containing all you need for running two 3D-Printers using two instances of [Octoprint](https://octoprint.org/download/) (OctoPi) on a Raspberry Pi 3+ (on different ports). Update 2019-11-01: Added "Big Box 2 v1.stl" - For the "other" relay board (better option). This gives the following: * Power-control / printer (ex. PSU and lighting). * LED-status (up to two ledstrips). * A Power button for the Raspberry Pi (real shutdown). * Two physical buttons to use for whatever you want (I use them to turn the power on and off to the printers). * Two AM2302 for monitoring temp and humidity (in an enclosure for example). What I used: * Raspberry Pi 3+ * [USB-Relay board](https://www.ebay.co.uk/itm/5V-USB-Relay-2-Channel-Programmable-Computer-Control-For-Smart-Home-UK-seller-/292838059668?hash=item442e822e94) (but I recommend an easier way with [this](https://www.ebay.co.uk/itm/5V-12V-or-24V-1-2-4-8-16-Channel-Relay-Module-Arduino-PI-ARM-AVR-DSP-PIC/262722739443?var=561656561192) board instead, With that board you don't have to use one USB-Port to control the relay. I just had the USB-Relay board already. As soon as I get my hands on the recommended relay board I'll add a STL-Box for that. Update: Added "box Big Box 2 v1.stl" * Two [Chassis Power Sockets](https://www.ebay.co.uk/itm/3pin-AC-IEC320-C14-Inline-Chassis-Power-Socket-Connector-10A-250V-Mains-Plug-2pc-/172264563795?hash=item281bc4a453) * One [Male Power Socket](https://www.ebay.co.uk/itm/1-2-3-5-10-Male-Power-Socket-Fused-Rocker-Switch-IEC320-C14-Inlet-Colours-New/222505789920?_trkparms=aid%3D555018%26algo%3DPL.SIM%26ao%3D1%26asc%3D40733%26meid%3D1ea3534f3060417e9a2bd5b5a1fb10ed%26pid%3D100005%26rk%3D4%26rkt%3D12%26mehot%3Dpf%26sd%3D172264563795%26itm%3D222505789920%26pmt%3D1%26noa%3D0%26pg%3D2047675&_trksid=p2047675.c100005.m1851) (with breaker): * Two [AM2302](https://thepihut.com/products/adafruit-am2302-wired-dht22-temperature-humidity-sensor), but you can use two if you want. * Two [Ledstrip](https://thepihut.com/products/adafruit-neopixel-led-strip-starter-pack-30-led-meter-black?ref=isp_rel_prd&isp_ref_pos=3) * Two green and one red [buttons](https://www.banggood.com/Wendao-DS-316-250V-1A-10mm-Self-Locking-ONOFF-Switch-Push-Button-Round-10pcs-p-1060415.html?rmmds=search&ID=228&cur_warehouse=CN) * Two [RJ10 female](https://www.aliexpress.com/i/32844256574.html) sockets (used to connect the AM2302 sensors). * Two [RJ10 male](https://www.aliexpress.com/item/32800860733.html) connectors (used to connect the AM2302 sensors). * One power regulator ([BEC](https://www.banggood.com/3A5A7A15A-BEC-Brushless-UBEC-For-FPV-Receiver-p-1007444.html?rmmds=search&ID=49920&cur_warehouse=CN)) * Two 10kohm and two 1kohm resistors (for pull down use). * Some cables of course. I use the following plugins in Octoprint (installed from the plugin handler): [Cancel Objects](https://github.com/paukstelis/OctoPrint-Cancelobject) [Cost Estimation](https://github.com/malnvenshorn/OctoPrint-CostEstimation) [Custom Background](https://github.com/jneilliii/OctoPrint-CustomBackground) [Dashboard](https://github.com/StefanCohen/OctoPrint-Dashboard) [DisplayLayerProgress Plugin](https://github.com/OllisGit/OctoPrint-DisplayLayerProgress) [Dragon Order](https://github.com/jneilliii/OctoPrint-DragonOrder) [Enclosure Plugin](https://github.com/vitormhenrique/OctoPrint-Enclosure) [Filament Manager](https://github.com/malnvenshorn/OctoPrint-FilamentManager) [Preheat Button](https://github.com/marian42/octoprint-preheat) [PSU Control](https://github.com/kantlivelong/OctoPrint-PSUControl) [Pushbullet](https://github.com/OctoPrint/OctoPrint-Pushbullet) [RGB Status](https://github.com/EricHigdon/OctoPrint-Rgb_status) The holes are made to fit M3 (just screw them in and let them "self tap"). You will have to drill your RPi:s holes to 3mm. :) I have not made the power to the raspberry come from the power plug to the printers. It's an "outside" power brick (12-24v) that powers the Pi and LEDs. Also, I've not configured the LED's yet.... This is not a "how-to" just information about what hardware I used to make it. You need to figure out how to connect stuff and configure the software of course. You can ask me if you have any questions! :)
