Pirelli Tire Stepper Ornament

Stock Prusa i3 MK3s+ 0.4mm nozzle0.2mm layer heightPrinting with this hardware setup tends to work ok, but due to the small detail of the text on the wall of the tire, a 0.25mm nozzle will give you better results. This model is based on the 13" wheels run for the 2021 Formula 1 season.  In this example, I've printed the black tire part in TPU, the red text in PLA and the white rim in PETG, but only because that's what I had available in those color combinations. In the photo, you may be able to notice the bit of tape on the end of the “axle” and that is there to take up the tolerance left in for less accurate machines.It is designed to accept a 6mmX3mm magnet which can be found all over the internet, but if you have something that's relatively similar, it should be fairly easy to design a new axle as I (hopefully remembered to) include the original Fusion360 files.The tire with the text imbedded in it is done in one print with a single nozzle! I used the technique detailed in this post by @rainer:https://forum.prusa3d.com/forum/original-prusa-i3-mk3s-mk3-user-mods-octoprint-enclosures-nozzles/simple-way-to-print-in-real-multi-color-without-mmu-or-layer-height-based-changes/It uses PrusaSlicer's ability to assign more than one toolhead and a custom “change tool” g-code to swap the filament mid print.  This can also be done in other slicers using a slightly different technique in MakeAnything's video here:Hopefully this is all the information needed to get you through this project, if not, message me here and I'll try and get back to it ASAP.  Happy Printing!
