Tennis Pen Holder

Hello guys i've designed this pen holder for a friend that is a tennis player and he loved it.

You have to print it and after slide and glue some 1,75 white pla in the recess of the balls.

There is also a Gcode pause for adding 4xM12 nuts for some weight, it's not necessary, it just give some premiumness at the print.

Hope you like it!
