Split Spinner Buttons - 15mm & 18mm

thingiverse

I create Spinners for my kids and every time I print spinner buttons, they require filling to fit. My solution is to take the Button and split the stem into four pieces. This approach seems to work well. I make two sizes: one with a 15mm top and another slightly wider with an 18mm top. I print them using specific settings - Nozzle at .4mm, Layer Height at .25mm, Infill at 50%, Top/Bottom Layer at 1mm, and Wall thickness at .8mm. I usually print them at 99% but note that all printers are different.
