This is a bracket to vertically mount your Extech Multi-Field EMF Meter (model EMF-450). Please note that I printed this and found that the meter fits rather tightly, such that it was somewhat difficult to get the device into/out of the bracket. I went back to the CAD software and “opened” the inside dimensions about a millimeter, so it should now be looser and probably perfect. However I didn't re-print another model as I was fine with the “tight” version. If you print this and find it's tight, please let me know and I'll open it a bit more.
The author marked this model as their own original creation.
