+# Zeta SBC
+3D Printable Enclosure for Zeta SBC and ParPortProp Based System
+
+## Description
+This is a 3D printable enclosure for Zeta SBC. This design is inspired by [OpenSCAD Parametric Box by FB Aka Heartman/Hearty](http://heartygfx.blogspot.com).
+I did a complete redesign to support the specific requirements I had for the Zeta SBC based system.
+
+This enclosure fits a Zeta SBC or Zeta SBC V2 SBC with a ParPortProp board mounted under it, and a 3.5" floppy drive mounted on top of it.
+
+I've included two front panel designs: The [first one](Zeta-Front-Floppy_with_Bezel.stl) works with regular floppy drives that
+have their own bezel. The [second one](Zeta-Front-Floppy_no_Bezel_Sony.stl) works with the Sony MPF920-L drive without bezel.
+It is assumed that for the Reset button Zeta SBC uses a tactile switch with the projected plunger and a 4 x 4 mm key top.
+Refer to [Recommended Electronic and Hardware Parts](#recommended-electronic-and-hardware-parts) section below for the part numbers.
+
+The boards and the floppy drive are mounted together using eight 15 mm standoffs.
+The board stack is then mounted to the bottom of the enclosure using 4 flat head M3 x 12 mm screws that go into the standoffs.
+The top part and the bottom parts are secured together using 4 flat head M3 x 8 mm screws going into threaded mounting holes
+on the sides of the floppy drive, and 2 flat head M3 x 6 mm screws and 2 sqare nuts placed into the slots in the bottom part.

+
+### 3D Printing Recommendations
+
+Print these parts with the "flat face" down. Use the "Rotate" function in your slicer software to rotate parts accordingly.
+The front and the back parts should be printed with the outer side facing the printer bed.
+Make sure to clean any 3D printing artifacts prior to assembling the case.
+Use a 3.2 mm (1/8") drill bit to clean the M3 holes in the top and bottom parts.
