Allis-Chalmer to John Deere Lustran Seed Plate Adaptor MC4300

thingiverse

A replica of the original part that you cannot buy any more for a local farmer. I ended up finding that this part is model MC4300 and is a Seed Plate Adaptor for Allis-Chalmer Seed Planters that allows you to use "B" type seed plates from John Deere Lustran to an AC (Allis-Chalmer) planter. I made this very strong with 7 walls and 5 layers on the top and bottom with 25% infill in hopes it will hold up to the rotational stress and wear that it will see. I may have to tweak that if it doesn't hold up. I attempted to initially make this out of PETG, but it warped and didn't turn out as well as I wanted. Due to the quick turnaround asked for on this, I didn't have enough PETG to try again, so I continued to make all of them out of PLA. Images show the original, PLA, and PETG. For reference, I did find a few places online that offered this for sale, specifically lincolnagproducts.com. Part number was AC-ADAPT and they sell it for $40 each.
