Digital Depth Gauge for router setting

Hello

I think that on most routers, it's not easy to set the bits position like with the Bosch Home and Garden router – POF series.

So if found some Digital Depth Gauges on several site like amazon or aliexpress, etc. (see the image with router (took from https ://www.youtube.com/watch?v=ACv_CpIGSdo)).

But because I already have a digital caliper, I designed this adapter to permit caliper to measure the depth and easily report it on the router bits.

I let a little loose to permit many caliper models to fit in.
To block the caliper, I used a screw M3x20
