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.

Good to know before you order

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 miniature piston keychain modelled after an internal combustion engine component, designed to be carried on a keyring or bag as a novelty item for those with an interest in engineering or motorsport. The design is split into separate parts, with two M3 screws and nuts required for final assembly. PLA prints this kind of small mechanical model cleanly and holds fine details well at standard layer heights.

Original maker's notes

By Tez_Gelmir on Thingiverse · CC-BY-SA

Miniture Piston Keychain has been modeled to have very low clean up required by adding supports & radii. I also separated the bigend to aid printing plus I think the little bolts give it a cool mechanical feel.

Parts Required:
1) 2x M3 x 10mm socket head cap screws.
2) 2x M3 nuts.

All should be available from a hardware store or fastening supply store.

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

Printing Piston Keychain (Low Cleanup)

For Piston Keychain (Low Cleanup) we would normally reach for PLA — it is the easy, economical default and suits the majority of models. 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.
