Mouse Bungee.

Optional: 

Hollow version For Adding/Removing Weight, I used steel balls and silicone.

Add “100% Silicone grease” to the threads for a smoother operation.

Add Velcro to the bottom for noise reducing or for more attachment options

Utilize the screw hole to attach it anywhere you like, for example under a desk or on a wall. 

My print settings:

Layer Height: 0,2

Perimeters: 3

Solid Layers: 3

Infill: 25%

Filament: NX2 PLA “PLA+”

No supports 

Troubleshooting: 

If you experience issues with the threads, try reducing or increasing the scale of one part.

Remember: Not all printers print the same!
