Collapsible / Spring-Loaded Hanger

Collapsible & Spring-Loaded Hanger:

This hanger was designed to collapse and automatically retract back into its original position when not in use. It was designed to make storing and fetching clothes much easier than your typical hanger. No need to pull the hanger off the clothes rod, just grab your shirt and go. The hanger was built for light-weight clothes (T-shirts, long sleeves, polo, and dress shirts) as sweaters and jackets are too heavy for the spring-loaded arms. 

The design uses two mechanisms to work properly:

1. Spring-loaded arms - These use a torsion spring and a hex nut to retract the arms back to place
2. Bump Stop - Small bump stops help keep the arms upright while carrying a load (clothes)  

Key Features:

• Collapsible for quick access to clothes 
• Spring-loaded arms return to its original position
• Same angle and length of a typical hanger
• Light but durable design
• Designed for easy printing with NO supports

This was a fun build focused on simple mechanics and usability. If you print one, I’d love to see how you use it and please share if there are ways to improve the design. 

Printing Instructions:

1. Print all parts in PTEG - I tried a test print in PLA and while it works, you can tell the torsion spring deforms under use
2. Use standard settings:
   • 0.2mm layer height
   • 15% infill
   • 2 walls for strength
3. No Supports
4. Ensure tolerances are clean—this design relies on smooth movement.

Assembly Instructions:

1. Remove all parts from the print bed and ensure everything printed correctly
2. Insert the two hex nuts into the front plate of the hanger
3. You'll need to make sure you install the correct arm in the location (see picture for spring direction)
   1. Align the hex nut with the hex insert on the arm
   2. The arm will need to be pre-loaded, twist the arm down and then push the arm onto the hex nut
4. The arms and springs should look like the following
   1. The springs should open up if the arms are push down
5. Install the back plate and screw on the bolts into the hex nuts
