3D printed LNL AP camwire bracket

So mine broke as well due to sticky primer slide tray.
Thought the original design needed some beefing up.
Got a cad model of the original on grabcad, 2 minute rush job change later sent it to a 3D printer and viola:

So far so good.

Awesome, are you able to make more?

Yes, off course, I would like to refine the design a bit though.
The effective depth of the hole for the cam wire wasn't deep enough and it can be optimised a bit using less material without sacrificing any strength. This was printed with pla.
The 3D printing guy will courier the part.

I really like the fact that you strengthen the part, I have had 3 break. not cool. Please let me know when you are ready and I will take 1.

Enhanced design has been completed.

Pm me your contact details and then we can arrange things.
Currently I don't know yet how much this one will cost to print but I estimate it won't be more than R300 delivered to your door if you are in Gauteng.

This part usually breaks if the primer punch does not fully retract after priming.

The locked primer slide then forces the guide rod towards the press body, snapping that piece.

You then have a bent guide rod, and maybe also have a primer punch with a bent or broken seater.

The primer punch will fail to retract if it has accumulated powder in it [ from spillage ] , or small metal bits from mis-seated / damaged primers [ which is an indexing problem ].

This part breaking is a symptom of other operating parameters that are no longer optimal, and if it does not break, then you will snap the primer slide and the seating pin in the primer punch, which are more expensive to replace than that plastic piece.

What material is used for printing this?

That I fully understand, but the standard part is just to weak imo and once damaged needs to be replaced, not so easy and convenient here in SA.
