Just a quick remix of jcohen313's awesome gyroid planter.

I figured it would be easier to print, if the arms could be printed separately from the main body. They can be attached with some super glue afterwards. If your tolerances aren't tight enough, just sand the ends of the arms down a bit, before attaching them.

I also recommend printing the main body with Cura's great "make overhangs printable" feature. That way you really don't need any supports and the planter still looks great.

I printed my Gyroid at 200% the original size.
