Bamboo Key Hanger – Impossible Passthrough

Created by Dotted Lines for the Makerworld Hangers Contest in August, 2024.

Not interested in the bamboo design? Check out my normal colorful version here. (Parts are interchangeable)

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!

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, and the other version can use double-sided mounting tape.
• Simply print one rack, and three keychains

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
