I printed the original vented case version of RandyR's thing but found that the size was a wee bit too small for my LMA4ALL board. This rework increases the internal dimensions slightly as well as increasing the wall thickness in order to provide a little bit more sturdiness. I also amended the clip pieces in order to make them more 3D printer friendly as the originals end up being printed in mid-air at one point.
One thing to watch out for should you also find the fit a bit tight are the points where the circuit board has been snapped away from its neighbours after the manufacturing stage - there can be small sticky out bits which can be carefully filed away.
I have removed the slot for power leads in the original as I power my LNA4ALL using Bias-T from my SDR dongle.
Print Settings
Printer:
Mendel90
Rafts:
No
Supports:
No
Resolution:
0.25
Infill:
20% but does not really matter
Notes:
This is a small box and therefore, infill settings are somewhat irrelevant - not enough space for the slicer to make any pretty infill patterns anyway.
My box was printed using ABS but any plastic will do the job. Note that there is no RF shielding - you may wish to use this box as a starting point for your enclosure project should you require it.Category: Electronics
