Don't cut those smooth rods, show your colours!
This is one of the first thing I designed and printed. If your printer is well calibrated you shouldn't have overhang issues like on my pictures.
I also reduced the insert's size by 0.25mm, hopefully your flags shouldnt crack like one of mine did. Let me know if this happens I'll reduce it further.
Printed with a .35 mm nozzle with filament from Ultimachine.
1-Print with a brim / skirt
3-Be gentle when installing the insert
4-Wear it with pride!
