thingiverse

This is a jig to turn standard craft sticks or jumbo craft sticks into amusing propellers that you can attach to dowels to make hand-powered helicopters or pinwheels. Print Settings Printer: FolgerTech Prusa 2020 i3 Rafts: No Supports: No Resolution: 0.4 Infill: 20% Notes: Printed in natural PLA on glass. Bed at 75F, extruder at 220F. This is about a 3.5 hour print using a total of 88 g of plastic. ABS will tend to warp unless you take special precautions like an enclosure. Post-Printing Making Propellers You can make propellers with either standard craft sticks or jumbo craft sticks. Mark the center of your stick by putting it in the template slot at the bottom of the jig, then push a 6 penny finishing nail point first through the hole in the middle of the jig. Boil your stick for about 30 minutes, making sure it is completely submerged in water. Put your stick through the slots in the top of the jig and let it dry overnight. Nail the stick 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 I designed this with BRL-CAD, an open-source 3D CAD system developed in 1984. This software is powerful and stable, but can be clunky.
