I have a Tekna DV-3X that I was using for a scooter project. I do not have time to work on it anymore, and don't get to go diving more than once or twice a year. I took the parts from the Tekna to build a larger scooter. I have 10 PVC for 2 body sizes. See the images below. I'm asking $200 OBO for the everything. Let me know if interested or have more questions.
