Tip for T5 Barrina grow lamp

Been printing this tower, but did had to buy different "grow lights". I found some T5 grow lights on amazon, 5000k I made them nice and snug, so they slide. I used the original tip and made some part narrow and longer for more support. (22mm). The hole that was provided was enought to plug in the wires of the lights, so I did not made any modifications. My first freecad cad project since high school... and its been a while!
