Parametric Rod for any type of pinwheel

I had the problem of having to glue the parts together to make the complete rod; the individual parts were too short, the mechanical play between the parts was too high, and it was difficult to get a straight and solid rod: in short, I was not satisfied.

So I modeled a single-piece rod from scratch for the most common bed sizes of BL printers, reinforcing the tip and hole into which either the pinwheel or another rod can be inserted to create a longer stick.

MATERIALS - pay attention!

In June, in northern Italy, PLA softened and bent. 50% of the rods printed in light green unfilled PETG bent. I am now printing them in black PETG+CF, which seems to hold up better. I have set a 20% infill which, with an 800mm long rod and a 100mm base, provides reasonable rigidity. Feel free to use the best infill for your climatic conditions.
