Thanks I took a look at the Vos-stock and the idea is really nice but a bit small, also I could like it to have the sphere hollow.I couldn't find anything like a Sphere in the OKB-1 thread except for Mulbin's design and one which was roughly the same (the idea). I tried out the B9 Aerospace pack and yes it has triangles though I have yet to find an equilateral one but I guess it could work with these. I'll put some work into it thanks! thanks I already knew that though!
