Made this parametric bushing mainly to imitate 608 bearings since 608 bearings are widely used in 3d printing world for parts or toys. 608 bearings also quite expensive depending on where you live (at least my area here are quite expensive too).

This is also a great thing to print because you're able to test your printer's tolerance capability. On my Prusa MK2, printing a single bushing only can go at 0.375mm while printing multiple of them able to go up until 0.3mm

I've included several models to be printed, T350 means Tolerance = 350 micron (0.35mm)

If you've found any bug or want to improve the script, do let me know in the comments section

these are also great to find out your printer's tolerance. link to test these bushings https://youtu.be/rXqle8XeVQY
