This design was carved out of Hoffman Tactical's v3.1 super lower.

The goal was to make decent trigger jig to use as a fidget toy or training aid. All of the other jigs I've found are junk. This one works great, so I figured I'd share.

The parts you will need are self explanatory. See misc. notes below for tips.

Use two large support blockers to avoid supports in the holes as shown in the picture, Otherwise you'll spend a long time removing supports or break the model.

I use 40% support density with 50% floor and roof density. 70° support overhang angle.

Be Very careful when tightening the grip. Preferably use a 1/4*28 tap in the hole before attaching the grip. If not, tighten very slowly and back out every 1/2 turn if it seems too tight. This model is prone to cracking if you force it.

In addition to the standard parts, I found that gluing a small piece of rubber on the front will absorb the shock without damaging anything. See picture for reference.
