3D Printed Impossible Passthrough Key Hanger by Dotted Lines
Printed On Bambu Lab X1-Carbon Using Filament eSun PLA+
Printed without Supports, Printed without Rafts, Infill 15 %
Dotted Lines 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!
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
