Just an idea I'm trying. Making houses out of a 3d printed frame and popsicle sticks.
Insert the popsicle sticks into the slots on one side and insert the little bars and glue down. The bars aren't perfect and may need to be sanded or clamped down. I used super glue to hold everything together. I then turned it over tucked all the popsicle sticks into the slots on the other side and glued that down as well.
