Really simple lure injector to print and assemble. I recommend ABS or any other material that can withstand the heat. It is 45mm in exterior diameter and 40mm interior, height 320mm. If you change the scale, check that there are at least 4 walls to avoid deformation. I added a tpu part which mounts on the slide but it is not necessarily necessary. I hope this model will be useful to you, good fishing.
