Made an angled bottle holder for Lucas Gun Oil. Gridfinity 1x3x4U with magnets. Pops in place, easy to get out.
After I printed for first time, I forget to more or less account for the negative angle of the mold (it didn't sit down forward past cap) took 4 hours to print so I just Dremel'd it out. I adjusted but didn't reprint, so I added .f3d file if not perfect. Good enough to keep for first run after Dremel.
