    Thank you! no, i wont print it, for i have no printer and besides, i am not sure if that model is suitable for printing because of all the tiny details and the holes in the body.

ID:	127125 Speaking of RPMtech, this started out as one of his series one Seehund hulls. Nothing left of it now, all repatterned- once i started tweaking this and tweaking that, it became clear the original kit was a little too stand-off scale for my tastes. Not the easiest boat to get right, as there were a lot of variations in the originals, and surviving examples have often been hacked about. Still a few details to add before pulling a tool from it. Seehunds are fun boats to drive, and this is a nice handy size at around 21.5".

            That is gorgeous CAD work, JHapprich! If there is any way to get a watertight shell out of the files, that's all that's really needed to take a crack at printing it off.

              Hello David Merriman, concerning that foxtrot of yours, did you construct a pivot mechanism for her forward planes or are those fixed? Im thinking about making Mike's forward planes fully functional, but my usual arrangement comes with working planes in extracted position only. I thought about trying something new now, maybe a miniaturized Engel design with the RME module. Regards Jörg

                The FOXTROT bow planes are operable for dive angle, but are fixed in position and do not retract. Sorry.

                  I see. Am not decided yet, very little space afterall.depends on how small i can make it without compromising stability

                    Jörg. A small recommendation if I may. I've had a lot of dificulty getting the Engle RME module to adjust correctly andwork consistently. In the end I threw two of them out and purchased a Bow Plane Interlock module (https://docs.wixstatic.com/ugd/856fd...0f29fcaeb6.pdf) made by Kevin McLeod and sold by NautilusDryDocks.com. That BPI is perfect. It adjusts easily and accurately and has never failed. Perferct.

                        No; not enough room. I used it on the Oscar.

                          Hello sir, I am going to make the Sierra I class submarine into 3D version, but I don't have the detailed section drawing, do you know where I can find the detailed plans?

                              X craft what type bob ? Your idea is great I thinking a long time to make a Database somehow but only for the members. Otherwise people come say hello take the files and never showed up again with results.

                                It's the earlier type, like the ones that rearranged the underside of the Tirpitz.

                                I think crowdfunding can work if you're paying a 3d artist to produce a file which can be printed. The cost of artwork split evenly amongst those who want the file, assuming there's sufficient interest,

                                If you're talking about manually producing masters, tools, castings etc. it's fraught with difficulties I think. For a start the masters would have to be produced to a consistent standard, then there are the issues of various parties keeping up their end of the bargain, plus the logistics of shipping it all about..
