Restarted the CAD work from scratch and this is the result to date. First of I am trying to get the overall shape and at the same time keep it printable. The finer details will emerge eventually as time passes. I have decided that I want to have the submarine fully "constructed" in CAD and possibly printed before the new year. Assembled maybe. Hopefully by then I have also figured out all the details needed for the R/C conversion. The build will most likely consist of roughly 9 printed hull pieces, 4 rubbers, 2 sail rudders and a number of beams for internal strengthening and WTC holding. That is the plan at least. Most of the parts will b printed in PLA. (obviously before it touches water the sub needs to be prepped, painted and sealed). The hull is 2mm thick at the moment.
The plan is to have the submarine i two parts, as usual, however I have as of yet not decided if the forward part or "nose" should belong to the bottom or the top section. If it were part of the top section I could slide it on and basically have one thumbscrew to fasten it all. What are your thoughts about that?
I haven't decided if I want to build the WTC on my own or buy one, but for the moment the 4 1/4 inch (108 mm dia.) OWT kit from Nautilus Drydock's should fit.
