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

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 mathematical art object based on the ambiguous cylinder optical illusion, in which the same physical shape appears to change form depending on the viewing angle and its mirror reflection. The design is generated using OpenSCAD and can be customised before printing. It is used as a desktop curiosity, a conversation piece or a demonstration of geometric perception. PLA is suitable, as the illusion depends on precise surface geometry rather than material strength.

Original maker's notes

By drjames on Thingiverse · CC-BY

This is my Ambiguous Cylinder Generator to create Illusions based on the ["Ambiguous Cylinder illusion"](https://www.youtube.com/watch?v=oWfFco7K9v8) by Kokichi Sugihara.

Use Thingiverse Customizer to Customize to your liking!

Have fun and share a make if you print one!

Changelog:
* v1.4: Presets for two kinds of illusions
* v1.3: Better Support Structure (should be easier to remove)

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

Printing Ambiguous Cylinder Generator

For Ambiguous Cylinder Generator 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.
