Sanding Wedge fully 3d printed

The thread in this version is not as strong as a normal screw but it worked for me. I had to screw it in a couple of times until it worked good.

I printed it as shown in the picture below, used a bit of support for the thread in the main part. 

I printed mine in PLA with a 0.6mm nozzle and 0.2mm layerheight. Use at least 3 perimeters.
