Assemble the model with some glue on the two major halves so they do not fall apart. The side door can be friction fit. Use support material, and I did not personally use tree supports for this model, as the clip mechanism may not print correctly. I used 35% infill to make a solid, and high quality part.
Please comment any corrections I should make to this model as this is my first attempt designing something of it's kind.
The author marked this model as their own original creation.
