RSLK-MAX reflection sensor holder

This is for RSLK-MAX (Robotic System Learning Kit - www.ti.com/rslk) reflection sensor holder. In original construction, sensor is approx 10mm from surface. By sensor datasheet optimal distance is 3mm. Original sensor has another problem: distance changes, when robot perform brake. To elimiate that problems, i'm added front ball caster (pololu-3530) and printed this holder. From sensor remove existing contacts and for connection to chassis board use some flexible wires (with connectors or not)
