This is a mouse bungee I made inspired by the Razer mouse bungee V2 but not expensive. Here's of video of it working: https://youtu.be/IuhN_GQQ2Ok

Here are the instructions:

1. You need to buy this spring and cut it in half so each length is 150mm:

If the link is broken here are the specs of the spring:

Tension spring Wire diameter: 0.8mm Outer Diameter: 7mm Length: 300mm (so each spring will be 150mm when you cut it)

2. Print the parts out and hot glue the springs inside of the holes

3. Use double sided tape to stick it to the desk

I hope you like the mouse bungee. If you have any questions send me an email at: mpkaye3@gmail.com.
