This is my 3D printed model of the Ha´tak class Pyramid ship from the series Stargate SG-1. Model is completely made by me with a sole idea to be assembled like a lego. No glue is needed at all. If you want to make it for yourself, here is a video that should help you with it:

The set of stl files includes two files with prefix "ccc" those are the joint pins but in this version, they are grouped together and a 0,2 layer is added so that they stick to the printing bed better. Pins 1 are made in group of four (you need 18 total) and pins 2 are grouped in three. (If you do not like it like that, you could use the version where are the individual pins).
