Yeah, cuz my guess of it being a tool to press t-molding into a corner is nothing like it being a tool to shape bondo into a corner... ::) Dude, I stared at that ---smurfing--- thing for far too long.

Finally got around to making these: My attempts at making larger threads failed, so I used a nut and bolt off thingiverse to just get it done. I envisioned a larger threaded post, but this will do. |

Hope no one's standing underneath that when it shears off. |
