Wow stick holder for #Gridfinity

Wowstick, Gridfinity, needs no further explanation.

Should be apparent that this needs no supports etc etc., don't print it upside-down because that would be mad, etc. etc.

Bit holes are 4.9mm which gives a GOOD amount of tolerance, at least on my MK3S with 0.6 nozzle and 0.4 layer height.

The model has holes for magnets should you stay awake all night worrying about whether it will fall over of its own volition.
