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

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 fully printable out-the-front style fidget mechanism that requires no rubber bands, springs or additional hardware. An integrated printed coil provides the spring action, and reversing the coil direction changes how the mechanism behaves. Edges benefit from careful deburring after printing to ensure smooth operation. PLA is the recommended material, as it gives the coil spring sufficient stiffness to function reliably.

Original maker's notes

Full printability without the need for additional components like rubber bands or springs.

The coil direction affects its function greatly. Be sure to try both directions.

ALSO, MAKE SURE TO DEBURR AND CLEAN THE 90° ANGLES

ESPECIALLY THE BLADE SO THE SPRING LOCK CAN CATCH
or enable Elephants foot settings so theres less to debur
