Fertilizer Cannula

thingiverse

Can be used to "inject" solid fertilizer into soil in a planter. Requires a skewer glued to parts of inner shaft to be completed. How to use: Stick into soil in assembled condition, remove inner part, input fertilizer, insert inner part again (push fertilizer out if easily possible), remove (while keeping pushing if not fully assebled yet), repeat at different location. Works best with fertilizer pellets of 5mm diameter. [Printed part was glued as another part failed within the same print and had to be reprinted in part]
