Could someone please help me figure out what exactly is non-manifold about my design? I've been using Sketchup, exporting as a Collada file, and everything (even much more complex shapes) have turned out fine.
Anyone wanna help me?
I've uploaded a Sketchup file as well as a Collada file if anyone needs them
Thanks a lot, VirtualV. The new part worked a treat.
I'll be sure to credit you in the description.
EDIT: Forgot to mention, i've now finished all the 'Magnen' parts necessary to then hopefully build a robot that turns into a magnet, based completely off of this picture (with some tweaks to allow for my very basic CAD skills): http://yugioh.wikia.com/wiki/Morphtronic_Magnen Thanks for your help.
