1:4 Gearbox (2-Stage)
thingiverse
I edited CharlieTCU's simple but excellent gearbox so you can stack them for a greater gear multiplier (or reduction if you go the other way) - the result being a nifty go-fasty spinny thing. With a prop on the output it makes a breezy fan. Print everything at 100% infill, except for the gearbox bodies which work just fine at 10%, for maximum sturdiness. You will need one of each item, with two exceptions: bolts and spacers don't require duplicates, but top plates should have an extra copy. Hopefully you can figure out the assembly from the pictures. It printed with spot-on tolerances on my printer, your luck may vary. Print Settings Printer: DaVinci Jr. Rafts: No Supports: No Resolution: 0.2mm Infill: 10%-100%
