80% arms Easy jig (gen1) to shop vac tool

thingiverse

I've got a new project underway, and it's been a wild ride so far. I just received an 80% lower receiver along with an upper kit, and I'm building a California-compliant firearm from scratch. The kit arrived a day early, which was a nice surprise considering the sweltering heat we're experiencing here - highs in the 90s have made it feel like a furnace outside. As I set up my workshop, I decided to tackle a few tasks while waiting for the heat to dissipate. One thing that caught my eye was the shop vac tube from Stinger, which doesn't quite fit my Rigid vacuum. To make matters worse, I realized I'd misplaced the adapter I had purchased earlier, so I needed to find a solution ASAP. After some quick research, I came across a design for print adapters that can be used with smaller vacuums (1.25 inch OD). The plan is to either print these or purchase them if my larger vacuum requires a different size. I'm also considering tweaking the design once I have access to my bigger shop vac. However, things didn't go exactly as planned throughout the day. Each and every print job was plagued by shifting issues during the first few layers, forcing me to improvise with a drill and a 1/4 shank round sander to remove the excess material from inside the print. It was a bit of a challenge, but I managed to get it done. In the end, this particular print took around 3 hours and 3 minutes to complete at a speed of 50mm/sec.
