The majority of functional applications take the form of a speed reducer, usually for a small electric motor or hand crank. But when designed correctly, printed gears can provide efficient and reasonably high load transfer and are an ideal solution for some applications. Of course printing gears using the commonly available plastics is a sacrifice in surface finish and durability compared to injection molded or machined plastic parts. Best of all, 3D Printers are common enough that a set of STL files can be shared with tons of people eager to use them online. The prototyping & creation process is quick & clean. Complexity & 3D variations are essentially free. Printed plastic gears are a cheap, quick, and customizable motion transfer solution compared to alternative ways to make gears. So why choose to 3D print gears over alternative gear making methods and what strengths does 3D printing offer? This will ensure that everything is securely held together. (The holes on the back of the plate may need cleaned up with a knife to aid this, depending on how good your printer is). Then align the bump on the clip with the hole on the back of the plate and press over the ring gear. Soften the clips using a heat gun for ~10 seconds. The wrench also holds the sun gear down onto the assembly.Ĥ. The glue is to keep the wrench attached to the nut.

Apply a smidge of clear drying glue (glue stick works well) to the business end of the wrench then install it from the side so it snaps on the nut. Pin the planet gears in place by pressing the nuts into the holes.ģ. (The pin on the sun gear is to the right and the handle of the ring gear is top and center.)Ģ. Clean up the gear teeth with a razor blade so they will mesh smoothly then place them on the plate in the same rotational orientation they were when you printed them.

The wrench file is the only one that needs print supports/scaffolding.Īssembly Instructions: (Read in full before starting)ġ. Any material will work as long as you can prevent warping, which would devastate this device. I recommend 0.3mm layer thickness maximum. Print all parts minimum 3 perimeters all sides top & bottom, with 15% infill. The largest printed part is 5.875" diameter)įor those without a 3D Printer: I am selling finished Geared Light Switch Covers on my blog here. (The assembled device measures 6.25" in diameter.Please don't use my files to compete with me.) (Please note the 'personal use only' licence for this design, this means- No Sharing, selling, or remixing to share/sell.The geared light switch cover is a neat example of something you should be able to design on your own after reading this instructable.įor those of you who have a 3D printer: you can find the STL files attached to this step for free! This Instructable is intended as a general guide for designing & printing FDM 3D printed plastic gears. While doing so I researched and collected notes on perfecting printed gears and I thought it was interesting enough to share. Everyone with a workshop or a garage got a custom geared light switch cover.ĭesigning this toy definitely took a few tries to get the desired effect. This past Christmas season I put my printer to good use making unique presents for my family.
