About this 3D model

My rubber band from my SIGMA stop ledlight was to short to my seatpost, so I've decided to create my own with more holes in it. I recommend to use TPU with shore 90A/95A/98A or 60D. Print with 3 walls, 3 bottoms and tops, infill 15% gyriod, 0.20mm layer height. It probably fit other lights or accessories.
