Again I had to change my tires from summer to winter. And again I forgot to by some chalk to mark the tire position. Fortunatly it is possible to design a 3D printed solution for almost anything.

Also a german version is avaliable:
VL (vorne links)
VR (vorne rechts)
HL (hinten links)
HR (hinten rechts)
It is designed to be printed with the letters to the bottom. They are strong enugh to be used 2x per year and not move much around. If you plan to move your tires much around you may design a remix to be printed with the layers in the horizontal.
