Could you please tag this with "rocket" ? It's hard to find...

unfortunatly the work computer that i did this on has a problem with the makerbot site so i cant edit the thing or the files or the name or anything :(.

but this was designed to fit a standard model rocket engine. i dont know yet if it is balanced properly or not but it will probably require support material to build. though i skeined it using support material and it got support all the way inside. Im planning on doing a skein with support and without and hand editing them together so i get support up to the base circle and no support after that.
