Anet A8 Electronics Case (mainboard, octopi, step-down converter, relay and fan.)

thingiverse

This is a completely rewritten version of a previous case for the Anet A8. I have thoroughly cleaned up the cases mounting and other areas, making significant improvements to its overall design. The cable opening has been changed, and some of the mounting locations have been relocated to provide better accessibility. A step-down converter mount and a mounting location under the raspberry pi's mounting location have also been added. This new feature allows for easier installation of the step-down converter, which is indicated by an arrow on the mount that matches the arrow on the converter itself. I have also incorporated fan mounting and covers into the design. Two sets of screws are included - one set with two attaching the fan to the case and two attaching the cover to the fan, while the other set requires M3x25mm screws to secure the cover directly to the case with the fan nestled between them. The arrow on this mount aligns perfectly with the arrow on the converter. Additionally, a hole has been drilled into the bottom right of the case (when it is standing upright) to accommodate the left z-axis motor's wires. Components recommended for this project include: * A Raspberry PI 3 Model B to control the printer * A Channel DC 5V Relay Switch Module for Arduino or Raspberry Pi/ARM/AVR, which allows the raspberry pi to power the printer on and off * A 6 Inch Micro USB Cable, which can be cut down to size if necessary to avoid clutter To drop the power from a 12V PSU to 5v for the Raspberry PI, an SMAKN 5pcs Mini MP1584EN Step-down Power DC-DC 3A Ultra Adjustable LM2596 is recommended. The full cover has been designed with a slim 80mm fan in mind. I opted for a Cooler Master Sleeve Bearing 80mm Slim Silent Fan to maintain as low of a profile as possible. Additional components required include: * x20 M3x6mm Self Tapping Screws * x4 M3x16mm Self Tapping Screws (which can be longer) * x4 M3x25mm Self Tapping Screws for fan use (or 8 if you prefer not to order separate screws) * (10) M3x25mm Hex Socket Tapping Button Head Black * Cable sleeving * Any additional components necessary can be sourced from eBay For anyone interested in similar projects, the following items are recommended: * Y Chain: http://www.thingiverse.com/thing:2043493 * Power Supply Cover: http://www.thingiverse.com/thing:2029520 * Mosfet Case: http://www.thingiverse.com/thing:2054199 Print Settings: Printer: Anet A8 Rafts: No Supports: No Resolution: .2 Infill: 100
