K-Pin is a push-fit pin to connect parts together. It has a specially designed section profile with a shape of "K". The profile is optimised for 3D printing by being more forgiving on tolerance.
Use the included K-Pin pusher to push the pins into sockets.


Print the parts in prepared orientation. Change filament color as you wish. The STL files consist of all parts at sufficient quantity.
The socket sizes for K-Pin in the design are all identical. Actual printed size of sockets might vary due to and filament shrinkage.

3D printing settings

No supports. At least 15% infill.
0.2 layer height for landing gears and K-Pin. Any layer height for others.
