The project files are organized into folders for easier printing and navigation. For that reason, stl file preview is turned off.
The models come in 2 versions - solid and hollow . Good thing is NO SUPPORT needed for any of it. The solid one is a super simple print you can print is fully combined or in 3 parts. The middle part has room/slot inside for something extra like the wire if you wish to take the prop to the next level. They both connect with 8x8 pins or 8x4 magnets if you wish to keep them apart/access the mentioned wire or led's. Speaking of led's - that's where the hollow version comes into play.
All the holes that emit light have been cut thru entirely and there are some extra slots for extra led's so you have quite some room to work with here. Same as the one before, they connect with 8x8 pins or 8x4 mm magnets so you can access electronics and the wire to make the prop even more badass.
