Case for ZX Spectrum Interface 1bis

A protective case for the back side of the Interface 1bis ver. 4c for the Sinclair ZX Spectrum.

Not a complete enclosing box, but for now rather designed to protect the back side against accidental shorts and static when my kids use the computer.

Version 3 onwards have enough room inside them that you can leave the optional I2C mounted inside, if like me you bought it for future use (pay attention to how the loose connector is placed to avoid shorts). Note: No hole for the cable has been designed in yet.

Version 4.1 should be used instead of version 3. It has a slightly reinforced bottom holding flap and some cosmetic improvements.

Version 4.2b has a hole for the I2C cable to exit through, and somewhat rounded corners. If you want to be able to pull the I2C cable out through the case or store it inside at will, this is the version you want.

Sketchup source and earlier versions included. Version 1 is not quite deep enough for the capacitors on the 4c, and the holding arms
