The UltraHDMI mod for the N64 is a great way to get N64 on a modern television.
The only downside was the dreaded cutting of the shell in order to accommodate the new miniHDMI port. While many people are more than willing to take a knife to their shell, some people would prefer to keep their precious console in perfect cosmetic condition.
The UltraHDMI #NoCutMod consists of two 3d printed parts. One part raises the UltraHDMI board to the correct height in order to clear the back of the bottom shell. The other part replaces the small piece that covers the multiout so that you can set that part aside in the event you want to revert the mod:

As an FYI, all of Greg’s designs can be purchased from his web store here: https://laserbear.net/
The downside to this particular mod is that you will need to modify one of your cables in order to get both output ports usable at the same time.
This mod has been tested with the Tim Worthington RGB mod installed, everything cleared and fit perfectly.
