Slime VR Tracker

I wanted to have my tracker as small as possible and light.
I could not find a model to fit a DIY build small enough so I made this.

For the people who don't know what it is:

SlimeVR is a set of open hardware sensors and open source software that facilitates full-body tracking (FBT) in virtual reality. With no base station required, SlimeVR makes wireless VR FBT affordable and comfortable.

Print recommendation:
Tough PLA
Layer height 0.2 or 0.1
Supports: No
Walls: 3
Infill: N/A

I was inspired by this model:
