Parametric Sensor supports for robots

If you have a robot and you want a support for sensors, maybe you have to design a support for each sensor and each position. With this, you don't need. The 3 supports that I added are:

- For Infrared sensors (Rectangular with 2 holes for bolts)
- For ultrasound sensors (Circular with 2 holes for bolts)
- For LEDs (Circula, only a hole for it)

To put in your desired position, the upper part of the support have holes (you can add more o remove holes), to introduce a bolt with tip
