Small Cutting Board Holder

I have a few different cutting boards, a lot of these small ones, I needed a hanger/holder for them and quickly designed up this one. All my board have a similar triangle shaped opening, even though they are bought in different places (Ikea some I believe). This fits them very well and sticks out about just over 5 cm from the wall, so I can fit 5+ boards on one hanger. I also have larger cutting boards, and they use this same hanger but fits a few less since they tend to be thicker. To check if your board fits, the opening should be more than 7cm wide, and 6-10mm tall or there about. The 3mf file has a print modifier to make it sturdy just at the base of the hanger. The holes are 5mm with a sunk in for screws.
