(sorry this is so long) I don't use 3D software, or own a 3D printer. I found the 3D file here for weaver passenger seats (1105) and want to send that to an online service to be printed. I tried to use a service recommended here, but the cost was around $120 for a single print. That would be "Per Car". So I found a service in China that if much cheaper, but the seats are too large because there is a group of three seat sections in the single file. They told me I'd have to break it up into single groups of seats (if that makes sense). Anyway, I've been trying the usual Freecad, Tinkercad and others, but because the stl file locks all the pieces into one single object, they cannot be broken up easily. I've tried surrounding the groups of seats with a hole, but then can't figure out how to make the hole disappear. I tried to contact the author of the file to see if he could break up each group of seats into separate files, but had no luck finding contact info. So, any ideas?
Thanks so much,
Bobby
