Modular Case for EBAZ4205 / Zynq-7010 FPGA Board

This is a modular screw-assembled case for the EBAZ4205 control board, originally used in the Ebit E9+ ASIC miner.

The miner itself is no longer particularly relevant as mining hardware, but its control board has found a second life in many hobby, FPGA, embedded Linux, SDR, and general hardware experiments. The board is based on the Xilinx Zynq-7010, which makes it a surprisingly interesting platform for various DIY projects.

I wanted to make a practical, printable enclosure for this board — not just a closed box, but a serviceable modular case with access to the most important connectors.

Design

The case consists of three main printed parts:

• Main body

• Top removable cover for access to the JTAG and UART connectors

• Side removable cover for access to the three DATA connectors

The main body includes openings for the board connectors, as well as a side opening for installing an external power on/off button.

The case is assembled using screws and nuts, so it can be disassembled when needed. This is useful if the board is still being modified, debugged, or used as a development platform rather than as a finished closed device.

Inside the main body, there is also additional free space of approximately 3 cm, intended for adding small extra modules, adapter boards, wiring, or other project-specific components.

Source files

The source files for the covers are included with the post, so they can be modified or adapted for your own needs. This may be useful if you want to add extra holes, change connector access, add labels, or adapt the enclosure for a slightly different project configuration.

Printing recommendations

I recommend printing the parts in PETG, especially if the enclosure will be used as a functional case rather than just a display model.

Supports are recommended due to the connector openings and the geometry of the case.

Suggested print settings:

• Material: PETG

• Supports: Yes

• Infill: medium to high, depending on expected use

• Wall count: preferably increased for better durability

• Layer height: use your usual functional-part settings

##Notes

This is a functional enclosure for a board that was never really intended to be a nice standalone development board — and that is exactly what makes it interesting. The EBAZ4205 is cheap, capable, slightly awkward, and very much alive in hobby projects.
