This case is for the following HDMI splitter: https://www.amazon.com/gp/product/B076JDXPRG/ref=oh_aui_detailpage_o06_s00?ie=UTF8&psc=1

This case is very snug for the splitter and will hold when all cables are connected. Since my splitter is going to be mounted in the garage, I used PETG. So, the tolerances fit. It has 6 recessed holes for mounting. You only need to use 1 or 2 holes. You don't need the strap, but I made it anyway. I printed the strap in NinjaFlex.
