I thought about how to increase the size of my smaller glider, which is popular in this venue. Each part is limited to approximately the table size of my Ender 3. So to a double the size of my original glider, I came up with a snap-together solution. 

The fuselage is made of two parts that snap together using three fingers and 3x1x2 mm extrusions. The left the right wing also snap together.  

The assembled aircraft's center of gravity is behind the wings, so it has a tendency to pitch up and stall. To move the center of gravity forward, I placed a 3 mm bolt and nuts in the hole and added 6 mm magnets to the receptacle on the nose.    This added about 6 grams to the nose.  Some clay or glued PLA might work just as well.

There is an optional low-wing forward cabin section, if you prefer that design  

i added 1 mm ribs to the aft cabin to stiffen it.

This is not a great flyer, but with the added weight in the nose, it does not pitch up sand stall.  

I would like to try to improve the flight characteristics by changing the thickness of each part from 0.6 mm to 0.4 mm in order to reduce the weight.  But this will have to come after the competition window closes.
