Hidden screw hook system. (Modular)

UPDATED. This is a lil passion project of mine that is seriously not as popular as i thought it would be.  But I don't really care. I use these all over my house and garage and they are still are going strong. I'm continuing to update it with different hooks and bases. Shoot me a message if there is anything in particular you think you might need/want or questions. THANKS! Print hooks as seen in pictures! Keep seams out of dovetail slip joint! Check back i will continue to update in the future.
