Print with support on inside only. For best results, use PLA+ and print at 100% infill with .2 layer height (.4 nozzle). I found this to be far superior to the garbage sold on Amazon that looks like it was speed printed with a .6 nozzle. Using PLA may make the inside pin fragile and cause it to break off. PLA+ has flexibility and increased strength.

Printed with an Ender 3 V2 using Overture PLA+ blue.
