M4 nuts holders for E3D V6 Bowden MODULAR X Carriage V4

thingiverse

So, I was getting fed up with my M4 bolts disappearing into the back of the print whenever I tried to attach the E3D V6 holder base, so I came up with this simple yet effective solution. This little gadget slips right in after the M4 nuts and makes it easy to bolt on the bearing holders. You can whip these out quickly using Vase Mode (or Spiral Mode, if you're a Cura user) for an effortless print that still gets the job done!
