Description

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.

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.
A1 mini users need to split the wings into two parts (can be done with Bambu Studio) and glue them together after printing.

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

Update 2023-12-11:

Thanks to sgioja and CatWhisker I was able to correct two design flaws (cockpit + wings) and re-oriented the wing support in the print profile. The STLs and the print profile have been updated accordingly.

Update 2024-02-17:
User doppelt-05 made a very creative add-on to this model. He added a pinwheel propeller so that the propeller spins when the wind is blowing.

@Rangebear

Great files. :) Did not print them on the Bambu, but awesome.

@blecheimer

Three of them? I guess you are starting your own airline... ;)

@Rangebear

Hah no, just 3 kids :)

For the A1 mini printer, you do not need to split the wings when printing, just print the upper and lower wings separately. If the upper wing exceeds the printing plate, use the scaling function in the software to reduce it to 98.89%. No other parts need to be scaled. a1 mini 打印机翼时，不需要分割，只需要将上下机翼分别打印即可。上机翼超出打印盘，的使用软件中缩放功能，缩小至98.89即可。其他部分都不需要缩放。

@blecheimer

Thank you very much for this hint! I did not know if scaling works.

@CatWhisker

I sent the plates to the printer as is. The wing support failed the first time around, so then I sent them to the printer just by themselves and slowed the printer down 50%. They failed again. Then I downloaded the raw files and oriented them so that they were laying flat instead of upright. They turned out fine with them oriented flat. Overall this plane is excellent, it just needs that one little tweak with the supports. Every piece fit extremely well and I love how you have included a screwdriver to put it all together. It's those little things that make all the difference. The plane is not flimsy at all and has some weight to it. I highly recommend to give it a go. You can play with colours and see how it turns out for yourself. Thank you blecheimer

Thank you for your comment! I like the way you have solved the support issue - that is the maker spirit! I will think about the orientation of the wing support and might update the 3mf file.

Happy New Year! But are you sure you posted the correct photo?

Sorry, I gave it to my brother but didn't have time to take a photo.

I loved putting this together for my kid. The design is beautiful and super easy and satisfying to assemble. The only complaint I have is the pins on the propeller and wheels break easily. I printed 3 times with increased wall count and infill but they still break easily.

Awesome model, very well designed. I printed on an X1C and A1. Had to make profiles for the A1 as it tried to print the wings off the bed using the original designer profile. I think MakerWorld have solved this now.
