FarmBot Extended Seed Trough for Gantry

thingiverse

My FarmBot Genesis 1.5 is attached to a raised bed which is about as wide as the unit supports. My Universal Tool Mount is [I believe because of this width] unable to reach the gantry-mounted seed trough that comes with the FarmBot. I started with the CAD drawing for the FarmBot Seed Trough ( https://genesis.farm.bot/docs/cad ) I extended it in both X and Y directions - problem solved. I also changed the positioning where you mount the seed trays. In the original trough, there was not enough space to have the seed tray handles extend in the same direction as the mounting arm. However, with the extended design, there is room. This not only allows the tray handles to be a bit more out of the way of the UTM, it makes printing slightly easier - the notches for the seed tray handles won't have support material. Update - I made this 10 mm longer because, when I reversed the position of the seed tray handles, I failed to take into account that the depth of the seed trays is variable and I want the seeding needle to be able to reach the deepest part of the seed tray. Final update (hopefully) - I think X dimension is finally right. On my Genesis 1.5, the needle descends into the deepest part of the seed tray.
