shower handle

the handle in the shower cabin broke, it was necessary to do it quickly. the internal landing square is 10x10mm. it sits very tightly. one screw m4 for assembly. PETG. 4-6 wall.

p.s. 
The handle is printed separately, for printing, divide the model into objects. The handle is on the grooves and sits very tightly. For easier installation of the assembled part, you can add a little scale. 
p.s.2 organic auto support are needed
