Summary

Add an access control turnstile to your railway or diorama. Scaled in 1-in-20. Rescale as required.

Print using high infill. Supports are not required. Print three rotting paddles.

1. Glue together the rotating paddle. File or sand the ends of the paddle to fit inside the bearings.
2. Glue together both frame pieces. Smooth the joint.
3. Glue the lower bearing to the static paddle.
4. Position the rotating paddle in the lower bearing and then glue the upper bearing to the static paddle.
5. Glue the frame to the upper bearing. This is a relatively weak joint - possibly join this when installing the turnstile to your layout.

Paint and decorate as required.
