iMatch bushing
The price on the iMatch bushings were far too high. I have used this printed in PETG on my rough cutter and sub-soiler and it has worked wonders so far. Even if it breaks once a year it'll take about 30 years before it would be worth it to buy the actual ones.
I do not recommend using on anything that puts high pressure on the implement.
Included in the file is one lower bushing and one upper bushing. The larger of the two is the lower bushing and you will need two for each implement.
