#FG085 Case & Hack Bill of Materials (BOM)

###Case (half-case, order 2 pieces)
I have had luck ordering 3D prints from Shapeways and MakeXYZ. Shapeways is more expensive but produces a more finished looking print. More specifically at MakeXYZ I have used a local printer, Jimmy Fakhouri, to make several cases. I highly recommend him.

###Case Screws (4)
The top and bottom halves of the case are held together with four #4 flat-head sheet-metal screws.

###Back Panel (1)
There are three options for the back panel.

  1. Use the back panel included with the kit. You will have to cut holes for the power and USB connectors if you want to add them.
  2. Use the enclosed .dxf file to order a back panel in 1/16" black acrylic from a laser cutting company such as Pololu. This part will fit in the enclosed case design.
  3. Use the enclosed .dxf file to order a back panel in 1/8" black acrylic from a laser cutting company such as Pololu. You will need to modify the case .stl file to make the channel that captures the back panel wide enough for the 1/8" acrylic.

###Spacers (4)
Digi-KEY #952-2313-ND HEX STANDOFF M3 BRASS 12MM
Use these spacers instead of the ones included in the kit. They go between the front panel and the PCB. Use the screws included in the kit. The screws that normally retain the back panel will now secure the PCB/front panel assembly into the case. You will only be able to put in two screws in the case but that is sufficient.

###Rubber Feet, stick-on (4)
Digi-Key #SJ5003-0-ND BUMPER CYLINDRICAL 0.44" DIA BLK

###USB pig-tail
Note that although I used a plug/header to connect to the PCB, you could just solder the ribbon cable directly to the board.

  • USB mini-B Connector (1) Digi-Key #MUSBB55104 CONN RUGGED USB RCPT VERT MINI B
  • Connector screws (2) Digi-Key #H700-ND MACHINE SCREW PAN PHILLIPS 2-56
  • Breakout PCB (1) OSH Park shared project #tosjrsDY
  • Ribbon Cable (6") 4-conductor, 28 AWG
  • 4-pin Housing (1) Digi-Key #952-2229-ND SIL FEMALE CRIMP HOUSING 4POS
  • Crimp Pins (4 plus spares) Digi-Key #952-2157-1-ND FEMALE CRIMP CONTACT SELECTIVE
  • 4-pin Break-away Header, 0.1" (one length of header at least 4 pins)

###Power pig-tail
Note that although I used a plug/header to connect to the PCB, you could just solder the wires directly to the board.

###Push-Button Switches
None are required but if you are looking to replace some of the ones in the kit or to use in another project you can find them at Mouser #612-TL2230-OA.
