Roller Gear
thingiverse
This Roller Gear was inspired by a design featured in "Making Mechanical Marvels In Wood" by Raymond Levy. The accompanying image showcases my initial interpretation of the design crafted from wood, and this current 3D printed version. Developed with smaller printers in mind, this implementation is tailored to fit within the constraints of a typical machine. The maximum X/Y dimensions are 100mm, while the maximum Z dimension reaches 44mm. To minimize material waste, I opted for Acrylic rods sourced from eBay (http://www.ebay.com/itm/302188063853). These rods exhibit varying thicknesses, which proves advantageous when searching for suitable sections to employ as press fits and sliding components on the same rod. A video capturing the gear in operation can be viewed on YouTube at https://www.youtube.com/watch?v=o9MS_LIVVr4.
