I'm still fascinated by the printer on a daily basis. When I think of all the things I have thrown away over the years because some cheesy plastic part broke and either you couldn't find one, or the replacement cost more than the whole item.
If you are into electronics ... you can print custom enclosures with any mounts, holes, battery trays etc. all at one time.
Come spring time the tractors and equipment are all going to get new shift boots, bumpers, rubber mounts, bushings, knobs, end caps etc. all that stuff that the sun destroys, or gets lost, or worn out.
Downside is you have to be fairly fluent in CAD software and have a decent PC to run it, to design custom parts.
Just designed and printed this
