I made a model that would clamp to Weaver rails and provide a vertical bolt hole. Weaver rails were the most common for firearm accessories, so paintball guns, airsoft guns, toy guns, and squirt guns all used them. I had to fudge some of the measurements since the patent drawings were intended for machinists, not modelers.
I wanted to create NERF-compatible accessory rails, but I did not immediately find any reliable resources, so I measured them myself. They were delightfully simple with 90° angles, and all dimensions were multiples of 1/8". I drafted a cross-section and clearly showed the sizes.
I addressed a couple of minor issues with the Weaver rail adapter model so that they would not interfere with the NERF version. The NERF model could have been narrower and longer, but I sized it to use the same 30mm bolts and short enough to fit anywhere on the gun I had. The prints fastened nicely on the first try.
I wanted arcade buttons on the pipes, so I created an adapter that would hold a flat button to a rounded pipe. The bolt holes are positioned toward the center of the pipe, ensuring the nuts and bolts sit securely when the holes are drilled.
I installed an arcade pushbutton on the side of a pipe with the help of the printed adapter. The next issue was a repeat of the last time I used the "threads" library, where I had to manually assign the thread pitch, or they would bind. The pieces fit better, but they still had binding issues.
We talked about Paul (2011), starring Simon Pegg and Nick Frost, and approximately 2,000 other celebrities, who have virtually every speaking role. I did not care for the movie because it lacked substance for me, but it was an easy watch. We acknowledged the problematic aspects that plagued Pegg and Frost for years before this movie.
The rest of the summary posts have been arranged by date.
