Pterodactyl

cults3d

A pterodactyl animated by the wind to act as a scarecrow and protect your crop, for example! A 2nd version is available here https://cults3d.com/en/3d-model/home/pterodactyle-vs-t-rex To liven up your balcony or garden, or simply in interior decoration with the manual wheel to activate the pterodactyl. All the assemblies are made with small pieces of filament of 1.75 mm, put a point of glue if necessary.I provided 2 kinds of blades, a larger one in case of weak wind. The propeller shaft has 5 holes more or less distant from the central axis to adjust the operation . First mount the pterodactyl with the wings and the piston, then insert into the body, screw the cam with an M3 screw of about 10 mm without tightening too much, make sure that nothing forces! I've added larger but thinner wings to reduce the weight and the impression. Addition of a 5 mm longer wing cam for more amplitude of the large wings. Addition of a 5-blade propeller hub 22/04 : added a pair of larger and thinner wings for more realism, see the 2 last pictures. Mounting Instructions : 1-Insert the cam into the plunger and insert a piece of filament through the plunger, cut flush. 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!
