I needed some monitor stands to get my screens aligned, but I didn't want to waste lots of filament making big parts and then finding I had mis-measured or had a printer malfunction. I looked at many designs on Thingiverse and my result is clearly similar to lookitsz' Monitor Stand, but what I came up with is more like a set of blocks and bridges to link them together.

The STL files are really just examples unless you specifically need a stand lo raise a Samsung SyncMaster S22B300 by 60mm. Instead the intent is to use the OpenSCAD modules and create your own set of linked blocks to make the support you need.

For example :

foot(notches=[1,1,1,1,1,1,1,1]);     // create a foot with all eight slots (corners and sides)
foot(notches=[0,0,0,0,1,1,1,1]);     // create a foot with slots in all four corners
foot(notches=[1,0,0,0,1,0,0,0]);     // create a foot with slots in one corner and one side
foot(notches=[0,0,1,0,0,1,0,0]);     // create a foot with slots in a different corner and side

bridge(len=155-footX);       //create a bridge to link two feet so the centers are 155mm apart.
        // (len is the distance between the foot sides)

Thus the feet can be specified to go anywhere in a 2D grid, linked horizontally, vertically or diagonally to fit design requirements or printer limitations.
