Here’s a shower toy to have a blast with. This will thread onto most any hand held shower hose.
Printed with ABS with the threaded end up, and supports at the bottom.
After printing, use a .125, or 3mm drill to open the water jets.
And of course, smooth and seal before use.
Width is 2.6″, or 65 mm, and length is 6.5″, or 165mm.
