This design it was done, to upgrade the A10, A10M, (Ender 3; not verified since I don’t have one at home, so if someone can verify if the design fits and inform me) and now also fitted it to my CR-10sPro and basically every printer when using the no attachment case, with the power relay feature to switch on/off the printer: https://github.com/caesar1111/Power-relay-for-octoprint-with-manual-buttons/blob/master/power-relay-for-octoprint-with-manual-buttons.md The design is featuring: - A modular mock-up designed to feature most of the common Ender 3 type designs - Base to mount the raspberry, the 5V power supply, the relay and the push buttons - Lid to mount the IEC 3 Pin 320 C14 inlet and with cut-outs for the pi cam to be used with octoprint - Snap in brackets to attach the base to the frame without screws (base comes with and without the attachment bracket rails) Additional parts needed: - Raspberry pi (https://www.amazon.com/ELEMENT-Element14-Raspberry-Pi-Motherboard/dp/B07BDR5PDW/ref=sr_1_3?crid=ASCCJI9LHXLQ&keywords=raspberry+pi+3+b%2B&qid=1553938182&s=gateway&sprefix=ra%2Caps%2C315&sr=8-3) - RS-25-5 power supply (e.g. https://www.amazon.com/MEAN-WELL-Switching-Resistance-Temperature/dp/B07BHQKNP1/ref=sr_1_1?keywords=rs+25-5&qid=1553617484&s=gateway&sr=8-1) - 2 channel relay 5V (e.g. https://www.amazon.com/Qunqi-Channel-Optocoupler-Expansion-Raspberry/dp/B078478SZ9/ref=sr_1_17?crid=CXURI6C091ZR&keywords=5v+relay&qid=1553608726&s=gateway&sprefix=5v+rel%2Caps%2C247&sr=8-17) - 3 pcs. push buttons (if possible with different colour) (e.g. https://www.amazon.com/URBEST-Momentary-Button-Switch-Pieces/dp/B01IU898QA/ref=sr_1_14?crid=2TF6BJU8SI5MC&keywords=button+electronic&qid=1553608797&s=gateway&sprefix=button+ele%2Caps%2C408&sr=8-14) - Micro USB power cable (https://www.amazon.de/Delock-82697-Stecker-Kabelenden-schwarz/dp/B01A9GLG6Q/ref=sr_1_1?__mk_de_DE=%C3%85M%C3%85%C5%BD%C3%95%C3%91&crid=14JZ99DCT82ZP&keywords=micro+usb+stromkabel&qid=1553938388&s=gateway&sprefix=micro+usb+stromca%2Caps%2C173&sr=8-1) (or just use a regular micro USB cable and clip of the USB side) - Some female to female jumper wires (e.g. https://www.amazon.com/GenBasic-Solderless-Dupont-Compatible-Breadboard-Prototyping/dp/B01L5ULRUA/ref=sr_1_3?crid=1GVJ0KXXOGT7X&keywords=female+female+jumper+wires&qid=1553616573&s=gateway&sprefix=female+femal+jum%2Caps%2C266&sr=8-3) - AC C13 power cord (https://www.amazon.com/10-Standard-Computer-Power-Cord/dp/B0002GRUIM/ref=sr_1_4?keywords=power+cord+c13&qid=1553939054&s=gateway&sr=8-4) or (https://www.amazon.de/Naths-Hardware-Kaltger%C3%A4tekabel-Kaltger%C3%A4testecker-Schutzkontakt/dp/B06XG6Z7NL/ref=sr_1_2?__mk_de_DE=%C3%85M%C3%85%C5%BD%C3%95%C3%91&keywords=c14+cabel&qid=1553939039&s=gateway&sr=8-2-spell) depending on your country you have to pick the right cord to match the requested wire diameters. - Some wire terminals to ensure proper connections for the AC high voltage wiring (e.g. https://www.amazon.com/Glarks-Disconnect-Electrical-Solderless-Connectors/dp/B01E4RAVI0/ref=sr_1_8?keywords=wire+terminals&qid=1553608962&s=gateway&sr=8-8) - 6 pcs. M3x8 screws ISO 10642 (lid) - 4 pcs. M3x15-20 screws ISO 10642 (power cord bracket) - 2 pcs. M3x8 screws ISO 7380, ISO 4762 or similar (5V power supply) - 8 pcs. M2,5x8 screws ISO 7380, ISO 4762 or similar (raspberry and relay) Optional 2 cooling fans: - 2 pcs. 40mm x 40mm 5V fan (https://www.amazon.com/GDSTIME-Small-Brushless-Cooling-Cooler/dp/B00MYZAGBW/ref=sr_1_5?keywords=40x40+5v+fan&qid=1553942559&s=gateway&sr=8-5) - 8 pcs. M2,5x20 screws ISO 7380, ISO 4762 or similar (fan) - 8 pcs. M2,5 nut Assembly: assemble case as shown on pictures. you might want to widen the holes for the screws with a drill (depending on the printing quality you select) or (as I prefer to do) before assembling anything to the case, use a blow torch to warm up the screw brackets and screw in the screws to gently form a thread inside the brackets. Let i cool down for a few seconds and undo the screw again. snap rail clips into printer rails. lift printer and let the clips glide into the brackets of the case. Release notes: In the V2 files I added an improved clip (old one was snapping) and a base with a cut-out to take out the raspberry microSD card without disassembly. In the V3 files I changed the fan grid to vertical slots for easier printing In the V4 mockup (FreeCAD model 8) version of the model I included an adapter for the genue Meanwell RS-25-5 which only has two threats on the bottom.
