Anet A8 Electronics Case

thingiverse

This thing was created since I couldn't find a case that would hold two mosfets (of the type I used) and the Anet mainboard. I either only found cases to hold the mosfet(s) or the mainboard; many also had space added for other circuit boards that weren't of interest to me. At a later date, I also modified it for a different type of mosfet and made it more flexible in its design. It's now possible to use it for one or two large mosfets (the kind I use) or for one or two smaller types of mosfets. I designed this to be as cheap and light as possible while still staying together. All the walls, bottoms, and lids are 1.2 mm thick, which might sound flimsy, but they stay together nicely. Since the printer bed can only handle 220 mm, I had to split the case into two pieces. By placing one of the mosfets in the divide, it helps holding the two pieces together. The case is created to work with the Hulk Braces, created by Leo_N (thanks for a great creation, Leo_N). The assembled case consists of two sections: a top and bottom. Just choose the desired setup that interests you. Each section consists of a case and a lid. There are also three different reset pins (20 mm, 21 mm, or 22 mm) for the reset button. Print them all and use the one that works best. These are the different combinations: **One large mosfet** * ElectronicsCase_Bottom_Lid.stl * ElectronicsCase_Bottom_LargeMosfet.stl * ElectronicsCase_TopSmall_Lid.stl * ElectronicsCase_TopSmall_LargeMosfet.stl **One small mosfet** * ElectronicsCase_Bottom_Lid.stl * ElectronicsCase_Bottom_SmallMosfet.stl * ElectronicsCase_TopSmall_Lid.stl * ElectronicsCase_TopSmall_NoMosfet.stl **Two large mosfets** * ElectronicsCase_Bottom_Lid.stl * ElectronicsCase_Bottom_LargeMosfet.stl * ElectronicsCase_TopBig_Lid.stl * ElectronicsCase_TopBig_LargeMosfet.stl **Two small mosfets** * ElectronicsCase_Bottom_Lid.stl * ElectronicsCase_Bottom_SmallMosfet.stl * ElectronicsCase_TopBig_Lid.stl * ElectronicsCase_TopBig_SmallMosfet.stl Then, there's the different reset pin files: + Reset_Button_Pin_20mm.stl + Reset_Button_Pin_21mm.stl + Reset_Button_Pin_22mm.stl For assembling the case with two mosfets, you will need the following bolts and nuts. If you decide on assembling any of the combinations with only one mosfet, you will naturally need less bolts and nuts. * 7 x M3x16 mm button head screws (cases to the printer) * 7 x M3x16 mm button head screws (case to printer) * 12 x M3x6 mm socket head screws (mosfets to case) * 12 x M3x6 mm socket head screws (mainboard to case) The mosfets I used, and which I call the "large" mosfets, can be purchased from many places online.

The mosfets that I call "small" is also available from many places online. For reference, see this link: [https://www.amazon.com/dp/B072FHQ5WJ/ref=cm_sw_r_cp_ep_dp_EwarAb71YC05T](https://www.amazon.com/dp/B072FHQ5WJ/ref=cm_sw_r_cp_ep_dp_EwarAb71YC05T). The assembly is pretty much self-explanatory, but I do have to mention how and why I designed all the screw holes too small. Most printers can't print small holes accurately, so I created all the screw holes with a smaller diameter than required for the screw to fit. If you want to use the reset button, you will have to glue the reset pin to the reset button (on the lid to the bottom case).
