Parametric corner brackets

I was looking for corner brackets and found the great design by 3D Workspace (https://www.printables.com/model/113989-corner-bracket-optimized-for-3d-printing), however it didn't fit the dimensions I was looking for. So I decided to completely overengineer a solution and came up with this parameterizable design.

There are two versions: One for button head and one for countersunk screws. Please shoose according to your use-case

The included Fusion files are a bit of a mess, but the follwoing values can be changed:

• Hole spacing: The distance between the center of the hole and the wall
• Hole Spacing: Metric values. Offset for through holes is added. For countersunk screws the sunk bit is adjusted as well
• Wall thickness: includes the thickness of the contact area and the strengthening bits

For the supplied stls the hole diameter and spacing are given in the file name (M4x20 = hole for M4 screw with a 20mm spacing)

It is possible to print the brackets standing up. However,  this creates a structural weakpoint near the screw hole. If you are after maximum strength you will want to print it laying on it's side. It is a bit trickier to print, but all overhangs are <45° so it should be possible with pretty much any printer.
