We didn’t design this model. It’s a community file from its original creator, and now and then a file has a fault that only shows up when we print it, such as walls that are too thin or parts that don’t join properly. If that happens we’ll let you know and try to fix the file, which can add a day or two. If we can’t get a good print from it, we’ll refund you in full.

TPU has a £11.50 print-order minimum. ABS, ASA, PC, Nylon and PETG-CF have a £46 minimum; PA-CF has a £69 minimum. Delivery is shown separately in your cart.

Need a few parts? Add them to one cart. One order minimum and one postage charge cover the cart: £6.90 for standard materials, £11.50 with TPU, £46 with ABS, ASA, PC, Nylon or PETG-CF, or £69 with PA-CF.

Please check the model files include everything you need before ordering. We print the files as published by the creator, so you receive the parts in the model, not necessarily a finished assembly shown in any photos. These are community designs by their original creators; we manufacture and post them but cannot guarantee fitment for your specific appliance or use case - check the original design page for compatibility.

About this print

A printable planetary gear assembly that uses gear bearings to connect the carrier to the planet gears. This approach reduces reliance on sleeve bearings, potentially lowering frictional losses in the mechanism. The gear ratio is marked directly on the model. It is a useful demonstration piece for engineering education or for anyone learning about epicyclic gear systems. PLA is adequate for low-load gear demonstrations, though PETG offers better durability if the mechanism will see regular use.

3d printed planetary gear with gear bearings connecting the carrier to the gear planets. This allows (potentially) for reduced frictional losses in comparison to sleeve bearing.

The design is a extension of Emmett Lalish's innovative gear bearing http://www.thingiverse.com/thing:53451 and also uses his pin connectors V3 library http://www.thingiverse.com/thing:33790.

The gear ratio is written on the using HarlanDMii Write library http://www.thingiverse.com/thing:16193

Formatting may have been simplified. These are the independent maker's instructions and fitment claims; Hark Tech has not independently verified them.

Printing Planetary gear

For Planetary gear we would normally reach for PETG — it is tougher and more heat-resistant than PLA, ideal for parts that take load or live somewhere warm. We set the layer height, wall count, infill and supports to suit the model and how you will use it, and those choices are already priced into your instant quote. Want a specific colour or material? Tell us and we will match it where we can.
