Quantum Tripod Quick Releae

This Project came about as I could not interlacement part for my very expensive Quantum Heavy Duty Tripod, plus the top part broke in half so I decided to replace the top section, and after about 2 prints and fine tuning the process I was able to get a replacement printed., the test print were printed with 15% infill, final print was done with 50% infill a I needed a stronger mount, that can with stand my MEADE ETX 70 to be mounted
