Giá đỡ ống luồn dây điện 1/2"

I made these to allow me to store my wood for my laser between to shelfs. The printed part goes into the end of the conduit and then screws in, there are 2 holes in the end for secure holding and they are tapered to assure the screw is flush. I made the bottom portion thick because my short screws would have still gone through the shelf and I did not want them poking out.

For max strength I suggest printing solid. They are long enough so you can adjust them up and down a little.
