Instructions

For the basic one, just download the .STL and print it. If you want to get fancy, you can customize it.

Here are the parameters:
//Width of bracket.
width = 15; // [2:25]
//Lenght of side reinforcement triangles.
side_len = 27.5; // [5:50]
//Height of side reinforcement triangles.
side_ht = 14.5; // [5:50]
//Length of horizontal base.
length = 30; // [5:50]
//Height of vertical base.
up_ht = 17.75; // [5:50]
//Thickness of base and side.
thick = 2; // [0.25:2.5]
//Thickness of side reinforcement triangles.
side_thk = 1.75; // [0.25:2.5]
//Radius of corner fillets.
fillet_rad = 3.25; // [0.5:5]
//Distance between end of horizontal base and center of horizontal hole.
base_hole_gap = 4.5; // [1:10]
//Distance between top of vertical base and center of vertical hole.
side_hole_gap = 5.25; // [1:10]
//Short axis (diameter) of screw holes.
hole_dia = 6.75; // [1:10]
//Long axis (length) of screw holes.
hole_wid = 9.75; // [2:20]
//Fudge factor to ensure overlaps.
dt = 0.1; // [0.001,0.01,0.1]
