This is a toy plane that is based on the famous Boeing Stearman Model 75 biplane.
https://en.wikipedia.org/wiki/Boeing-Stearman_Model_75
The toy plane has a wingspan of 240mm and a length of 196mm. It can be completely assembled without using glue. All necessary clips and bolts are printed. I even included a small screwdriver.

Use the following settings for the wings: 0,12 layer height, 4 walls, 4 bottoms, 8 tops, 16% gyroid infill
The rest can be printed with 0,2 layers, 4 walls, 4 bottoms, 5 tops, 6% gyroid infill.
I recommend a brim only for the bolts. See my 3mf for more details and how I positioned the parts on the build plates. The 3mf file can be used with OrcaSlicer or Bambu Studio. I added a picture so you can see the orientation of the parts on the print bed.

Print the following parts with support:

• Fuselage (only for the cockpit)
• Wings (only for th bottom of the threads)
• Engine (not for the thread)
• Bolts (only for the head)
• Struts (use small tree support)
• Supports (use small tree support)
• Cockpit (only for the bottom of the thread)

Do not use support on the threads.

All parts will fit into a 200x200x200 build space.
Users with a smaller printer need to split the wings into two parts (can be done with the slicer) and glue them together after printing. Alternatively the model can be scaled down a little bit. I did not try this myself but I know there is a print that has been scaled down to 82%.

For assembly follow these steps:

• put the front cover on the engine
• screw the engine to the fuselage
• insert the cockpit into the fuselage and secure it with a short bolt
• insert the lower wing into the fuselage and secure it with a short bolt
• insert the rear wing into the fuselage and secure it with a short bolt
• this is now a bit tricky: insert the middle supports into the fuselage and put the top wing on the supports
• now put one strut between the lower and top wing
• insert a long bolt through the lower wing into the strut and screw it to the top wing
• repeat for the other side
• clip the propeller and the wheels with the pins to the plane
• make funny engine noises and play with your new plane
