Handle for Skimmercover

We have an Skimmer, but it was really hard to open and close the cover - cause there is only a hole (this I closed using the green tape - you can do more professional if you want).
So I just made an small handle to make handling easier.
Additionally you need:
2 x screw M3 x10 (stainless steel)
2 x square nut M3, 5,5 x 5,5mm, height 1,8mm

I recently added an solid version, so this could be easier to print.
Just have a look on the stl-files and you´ll see.
