Tiny Voltmeter Case

I designed this case to suit the miniature LED voltmeter displays readily available on Amazon and Chinese sites.

This is the description from Amazon.
0.28 Inch Mini Digital Voltmeter with 7 Segment LED Display 2.5V - 30V, Voltage Display.

They come in Red, Green, Yellow and Blue.

The case dimensions are tight with close fitting tolerances. Depending on the printer/PLA it may be necessary to scale up the model very slightly
and this can normally be achieved in the slicer software.

Optional 2x M2.5x6 fixing screws.

I use them with crocodile clips for in-circuit voltage display whilst fault finding circuits.

They can be calibrated with the SMD potentiometer in the centre of the board.

Printed in 0.2mm PLA, no supports needed.

I've included a STEP file as well as an STL so alterations, if required, will be easier.

Hope this helps someone.
