Duet WiFi Case Assembly | CR-10S 3D Printer

grabcad

This has been a long work in progress but I have finally finished the first working prototype for my Duet WiFi case. The intent behind this specific design was to be able to enclose the various electronic components that are utilized in my highly modified CR-10S. I was able to wire and contain everything in an organized way by using a combination of flex guard convoluted tubes and zip ties.**FYI: This build requires almost a full kg of filament depending on slicer settings. So be sure to have a full roll of filament ready and make sure your printer is dialed in before attempting to print these large components.**This case is designed to contain the following components:**1X Duet WiFi Control Board**https://www.filastruder.com/collections/electronics/products/duet-wifi**1X Solid State Relay**https://www.amazon.com/gp/product/B0087ZTN08/ref=oh_aui_detailpage_o01_s00?ie=UTF8&psc=1**1X Heater MOSFET**https://www.amazon.com/gp/product/B01MU3H01A/ref=oh_aui_detailpage_o03_s00?ie=UTF8&psc=1**2X Power Switches**https://www.amazon.com/gp/product/B00NWO68JI/ref=oh_aui_detailpage_o06_s00?ie=UTF8&psc=1**1X Power Supply**https://www.amazon.com/gp/product/B00IF93H6W/ref=oh_aui_detailpage_o08_s00?ie=UTF8&psc=1**2X 40mm Case Fans**https://www.amazon.com/gp/product/B009NQLT0M/ref=oh_aui_detailpage_o04_s00?ie=UTF8&psc=1**1X 50mm Case Fan**https://www.amazon.com/Noiseblocker-NB-BlackSilent-Ultra-Silent-3000rpm/dp/B0083A0CBG/ref=sr_1_1?s=electronics&ie=UTF8&qid=1526523975&sr=1-1&keywords=noiseblocker+fanI have personally made my own board to handle the 24V to 12V step down for case fans and the inductive sensor using the following transistors(https://www.amazon.com/gp/product/B076R44FS7/ref=oh_aui_detailpage_o02_s00?ie=UTF8&psc=1).

However, it is still advised to be CAUTIOUS when moving the assembly as an adequate amount of weight will be cantilevered off the edge of the frame. **DISCLAIMER**: I claim no responsibility for any damage that may result from assembly and wiring of electronics incorrectly, or drops resulting from inadequate mechanical fastening.**3D CAD Design Credit**Duet Wifi_Phil Maddox - GrabCADDC Power Supply_Luca - GrabCADURBEST Power Switch_Richard Bruning - GrabCADUxcell SSR_Xinchao Song - GrabCADFlexible Motor Coupling_Eoghan O'Duffy - GrabCADNOCTUA 40mm Fan_Sean - GrabCAD*Assembly Instructions*- Fasten the Base Mount and PSU Mounts to the CR-10 frame with machine screws and T-Slot Nuts (Optional).- Fasten the SSR onto the Base Mount next and make sure to connect all wires to it at this time.- Fasten the MOSFET board onto the Base Mount and connect all wires to it at this time.- Fasten the 4 case posts (CAREFULLY) into the Base Mount.- Fasten the Duet Wifi on the case posts with the plastic washers and machine screws. Be sure to hold each of the case posts while doing this as the external threads on the posts can break if not careful.- Install and fasten the power switches and case fans onto the Hinged mount- Install the Hinged Mount to the Base mount. The orientation is specific as this can be installed only one way. Do not force these pieces together.- Install Power Supply to the PSU Mount and fasten with machine screws.- Finish all remaining wiring until satisfied and close the case and secure with a zip tie (Optional)Enjoy the clutterless work area!
