Split Spinner Buttons - 15mm & 18mm

I have been making Spinners for my kids and every time I printed spinner buttons they needed filing to fit.

My solution was to take the Button and split the stem into 4 pieces. Seems to work well.

I made 2 sizes one with a 15mm top and one a little wider with an 18mm top.

I print them with

Nozzle .4mm
Layer H .25mm
Infill 50%
Top/Bottom Layer 1mm
Wall .8mm
I print them at 99%, but all printers are different..

Enjoy
