Tiny Corner Clamp

thingiverse

I work with 1/2in plywood often and my regular corner clamp is too cumbersome to use. I designed this clamp specifically to hold 1/2in plywood together until I get longer clamps on the joint. Materials needed: -45mm long M5x0.8mm hex head screw https://www.mcmaster.com/91287A331/ -M5 washer https://www.mcmaster.com/93475A240/ -M5 hex nut https://www.mcmaster.com/91828A241/ -Super glue To assemble: 1. Put a drop of super glue in the knob hex insert 2. Push 45MM hex bolt into knob and ensure it's straight 3. Dab tiny glue drops where the washer will sit and put the washer on to be set 4. Let glue dry completely 5. (Optional) Use M5x0.8mm tap to clean the thread of the hole on the bottom 3d printed piece 6. Screw in the bolt about 3/4 of the way 7. Insert hex nut into slot on 3d printed clamp head 7. Put a drop of super glue in the threads of the bolt nearest the tip 8. Turn the 3d printed piece with the bolt and nut upside-down and start screwing them together (you don't need to go too far with screwing the bolt into the nut, the idea is the bolt stops before the end of the nut threads 9. Let dry and test out the movement The nut is supposed to be free moving in the 3d printed head piece to allow for proper action while loosening/tightening the clamp. Turning the bolt is made significantly easier if you tapped the thread on the bottom piece. I had modeled the threads in, but 3d printing still isn't the most accurate of things.
