18:T49d,This is a simple design mostly for glass whiteboards that utilizes suction cups to keep it in place. Print with the back side facing down at a 45° angle. There is a magnetic version that contains captive magnets to be able to use on a traditional magnetic whiteboard. [Suction Cups](https://www.amazon.com/gp/product/B08VNW833N/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1) (1.77 Inches / ~45 mm) [Magnets](https://www.amazon.com/gp/product/B00HA2ARZO/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1) (10mm X 3mm) **Note: I highly recommend rare earth magnets as they will be strong enough to hold the shelf up. **
