Craft Stick Propeller Jig

thingiverse

This is a jig to turn standard craft sticks (popsicle sticks) or jumbo craft sticks ( tongue depressors) into amusing propellers which you can attach to dowels to make hand-powered helicopters or pinwheels.

This is about a 3.5 hour print using a total of 88 g of plastic. Because of this print's size, ABS will tend to warp unless you take special precautions (e.g. an enclosure) Post-Printing Making Propellers This uses either standard craft sticks ( 113 mm x 9 mm x 1.5mm) or jumbo craft sticks ( 148mm x 17 mm x 1.5 mm) to make propellers. Mark the center of your craft stick by putting it in the template slot in the bottom of the jig, then pushing a 6 penny finishing nail ( 2.6 mm x 63.8 mm) point first through the hole in the middle of the jig. Boil your craft stick for about 30 minutes, making sure it is completely submerged in the water. Put your stick through the slots in the top of the jig and let it dry overnight. Nail the stick through your center mark to the top of a 5 mm dowel to make a helicopter. Drill a 1 mm hole through the center, thread the prop onto a nail and add a bead for a spacer, then nail that to a larger dowel to make a pinwheel. How I Designed This Design Designed with BRL-CAD, an open-source 3D CAD system developed in 1984. This software is clunky, but powerful and stable.
