If you have the KY-008 laser module for your Arduino (or other development board) and the corresponding laser sensor, it can be a pain when testing a circuit sometimes as you tend to run out of hands. This set of 3 pieces will hold the laser the sensor and allow them to be slid into a base which stands on its own. The laser is aligned with the sensor (which is slightly offset from centre). If you need to test further distances you can just scale the z axis up on the base on the slicer. The modules are not super tight so they can easily be inserted and removed. If you have any variation that you would like me to adapt this model for just let me know.
