10mm No Drop Nut for 1515 extrusions

I found the 12's to be a bit too long back-to-back for some locations. They print super fast. Use your material of choice, I use ABS for my builds. Use the extrusion factor to adjust the fit as needed. Don't be afraid or too proud to use some glue stick, it only takes one of the parts coming loose to wreck the whole plate. Running at a slower speed will really help to ensure a good print.
