In my quest to Gridfinitize(?) the mountain of garbage that is my desk. I needed a phone holder that could accommodate a charging cable.  The few options that exist didn't have clever cable concealment (love that alliteration).  I started with a phone holder design I did like from jagdeepnaik.  I took that model and squished it on a 2x2x2 Gridfinity block and behold!  

The one down side is that it does require supports but they remove easily.

The red semi-transparent glittery goodness I printed this with is Fusion Filaments Reactor Red HTPET+ on an Ender 3 S1 Pro.

Interested in Gridfinity?
