1-500 MHz Frequency Counter 3D Printed Case

 

I picked up one of the inexpensive LCD frequency counter modules. There’re available from a number of sources like ebay, aliexpress, Amazon, etc. for less than $15.

 

 

 

 

Here’s the link to the module on aliexpress:

High Accuracy And Sensitivity 1-500 MHz Frequency Meter Counter Module

 

 

I designed a case using Sketchup.

 

 

Sketchup file – front:  freq-counter-case-v2.stl  (size: 71 KB)

 

 

Sketchup file – back:  freq-counter-back-v2.stl  (size: 49 KB)

 

 

The case was printed in PLA on a Printrbot Metal Plus 3D printer with 100% fill.

 

Here is the finished printed case that holds the module and 9V battery.

 

 

 

 

 

 

The back is attached with 2-56 x 3/8” machine screws. I used a #50 drill bit to enlarge the holes and ran a 2-56 tap to make the threads.

I picked up a Telescopic antenna with a SMA male connector from aliexpress.
