15mm thick canva wall hook (for adhesive)

I found a ton of my old oil paintings from when I was a kid and I wanted to proudly display them however any type of nail or hook currently available in house or for print doesn't really work as canvas don't really love getting hanged by nails. So i took some quick measurements and came up with this. 

This has only been tested with canvas with a 15mm thick frame with a the gap between the canva and the frame of 4mm. Please Let me know if a version for nails is wanted
