How does the Nut free prime rail attach to the blaster.

The nut helps keep the screws that mate with the bold sled in place. All the arms attach to the shell in the same way, using the original screws that hold the priming slider in place!

What grip do you have in the pics?

I am using the MagPul Rail Vertical Grip! It is not 3d printed.


I figured as much, thank you! Also printed the pump and its pretty awesome ^-^

i need one arm for the other side or what is wrong can you post an photo of the other side

What are you using for a slicing program? You should be able to easily mirror the arm in the slicer in order to print the other side.

This is awesome! Have you tried printing the arms in something stronger like nylon or PC ? If not I will try it and let you know.

I have only used PLA with good results. I placed a 7kg spring and the reinforced arms are able to take the load but I need to drill the holes out a bit larger for the retaining screws. I had a crack from at that point. Also your print orientation will make a difference too. Bottom down should give the pins more resistance to shearing. Good luck and be sure to share your results!
