The PACOH - Parametric Corner Hole Guide Bracket - (also as open version)

I needed a guide for fast drill holes marking. So i made a little parametric helper. Should be easy to print. You can adjust the number of holes, the height, the lenght, and the thickness. Feel free to remix it to your needs.
 

I also added a open version if you like to use it along the edges.
 

If you dont use Fusion 360 just ask for brackets i can generate and upload for you.
