I needed some new target stands for shooting practice, so I whipped up some in CAD. They are designed to be made out of 1/2" thick MDF. These 6 pieces build a base that is about 35"x30", and leave a slot to stick a 24" wide piece of 1/4" thick plywood (or cardboard) in. Most man-sized targets are around 23"x35", so just cut a sheet of 1/4" plywood into four 24"x48" pieces to use as backings, or rip it in half lengthwise for up to an 8' tall target. They weigh only a few pounds, and can be dis/assembled quickly so they take up very little room in the car.
The first CamBam (.CB) file is the parts for 1 stand, which fit in about a 36"x40" square as I have them arranged. The second CamBam file is a whole sheet of MDF that makes 3 stands. Then of course there is the DXF, which you can do with as you please.
