I want to clarify that I am not the author of this, it is Tomson, whom I thank for giving me his permission to post it !

These are wedge for the smooth rods of the X axis.
The original smooth rods measure approximately 280mm, and on the Prusa mini Bear, ideally, these rods should measure 300mm in order to fit all the way to the bottom of the X axis supports. To compensate for the 10mm missing on each side of the these smooth rods, Tomson created these wedges which works great!
It will therefore be necessary to print this model 4 times
The author marked this model as their own original creation.
