Handheld Precision Planetary Gearbox
Here's a random fun gadget for those those who went the extra mile in tuning their printers. Gearbox has ratios of both 3:1 and 4:1 depending on which parts you hold still.
THIS DESIGN MAY NOT WORK FOR YOUR PRINTER WITHOUT ADJUSTMENTS.
Parts have been designed to be 0.3mm larger. This should be taken taken into account when printing.
This gearbox was specifically made to be a benchmark/test print for well-tuned Ultimaker 2 printers using Simplify3D as the slicing engine.
If you are unable to assemble the parts as shown or if there is any backlash in the assembled gearbox, you will need to modify the design files/change part dimensions to fit your printer.
Comments here will (probably) be ignored. Please email me if you have comments, questions, concerns, complaints, etc.
