7/3/2015: Finishing last truss now - had to make a small mod. Uploaded picture of what I have printed today. 6/28/2015: Not floating yet but figured you'd like the updates now rather than later. (Had to make the pontoons much bigger for more buoyancy) 6/24/2015: Going to lay off the updates here until I get a floating platform. My blog where I'll post updates. http://mattkaras.com I'm trying to build a lower cost ROV so I can check out stuff underwater with a dropped camera via a tether from a surface unit. Please leave comments - as this is a work in progress. 6/22/2015 Update 0: Uploaded pontoon for the surface unit. 6/23/2015 Update 0.1: Added slot so pontoon doesn't have a 90deg overhang when printing. Also added truss portion.Here's my working bill of materials so far. https://docs.google.com/spreadsheets/d/1ICDtXc9yZ6EMcTCAZz07dDiNIeln_uMMD4zR5T9lR9s/edit?usp=sharing
