Key Hanger V2 - Impossible Passthrough

Whats new in V2? Overall the design is much more functional while also adding new features: New Print-in-place Center Column

- Much easier to thread into the hanger, and adds more ‘fidgetability’.

- You can now hang or remove your keys without having to twist the keychain

- No more issue at some angles where the keyring gets stuck or sticks out

- It always rotates and sits perfectly vertical.

- Redesigned wall rack for strength + easier printing,

- Improved tolerances so no more stuck keys

- Slightly smaller design despite these new features

Key Hanger V2 – Impossible Passthrough Created by Dotted Lines for the Makerworld Hangers Contest in August, 2024. New & Improved version of my design: Key Hanger – Impossible Passthrough

I love the recent trend of ‘impossible passthrough’ objects, but they have been limited mostly to toys and sculptures. I set out to create something functional with this technique – and I settled on a key hanger and key chain. The ‘passthrough’ portion features extra struts which make it much easier to print, and they keep the rack strong with continued use. I hope you enjoy, please like & boost if you’d like to see more models! V2.1 Edit: Added slight tapering to the end of wall rack - it's now easier to thread without lining up

V2.15 Edit: Uploaded extra profiles for each printer, added .STEP files for anyone remixing V2.2 Edit: Added new print profile for larger/wider keyrings V2.3 Edit: Fixed hole spacing on the screw backplate version

Compatible with all Bambu printers: X1 series, P1 Series, A1, and A1 Mini

Instructions

- In the 3mf file there is a version of the rack with and without screw holes.

- The screw hole version is designed to fit #2 wood screws (should fit most wall anchors as well), and the other version can use double-sided mounting tape.

- Simply print one rack, and three keychains

- There are two plates for keychains: single color, or print-by-object for easy multicolor

Tips

- If you encounter stringing, you may want to use a blow torch or heat gun to quickly remove

- Like most pasthrough objects, any friction will loosen over time

- If you have issues with the keyring breaking, I recommend checking out the print profile created by 3DWill here

What if I already printed V1? Unfortunately those parts are not compatible as the tolerances and size have changed slightly

Print Settings (recommended)

- Avoid crossing wall

- Slow speeds

- Reduce infill retraction - no
