3D model description

A remake of my first version with modification of the longer propeller axis, the t-rex to better take the wind direction and the modified bearing support.

The other parts remain unchanged.

Different sizes and shapes depending on wind and exposure, no need to print all the parts! Many of them are similar except for a few details, so make sure you visualize the parts you need before printing.

The people who bought the first version will be able to ask me for the additional files by sending me a message with their email address .

Don't hesitate to send me a message (with your e-mail) for a possible modification of one or more parts.

Mounting :

1-Insert the cam into the plunger and insert a piece of filament through the plunger, cut flush.

  1. 2. Assemble the wings on the body with 2 small pieces of filament by forcing a little bit, the wing has a smaller hole to wedge the filament.

3-Insert the wing cams into the piston, always with a piece of filament cut flush.

4- Insert the propeller shaft into the piston body.

5- Insert the piston in the piston body and connect the wing cams to the wings with a piece of filament after inserting the support rod of the pterodactyl body in the slot provided.

6 Screw the piston cam on the propeller shaft with a 10 mm M3 screw, start with the hole closest to the center, you can modify afterwards to change the amplitude of the wings according to the wind and the location of your pterodactyl.

7- Nesting the blades in the hub then clip it on the propeller shaft.

8-Insert a 22 mm ball bearing on a 6 or 8 mm threaded rod with a nut on each side.

9-Insert the rod in the bearing supportV3 then clip the support on the piston body.

10- your pterodactyl is ready to work!

Depending on the printing quality, it may be necessary to put a few dots of glue on some parts (blades, hub...).

Make sure all moving parts work freely!
