1515 Aluminum Extrusion Cap

Cap collection for 1515 (1-½") aluminum extrusions. 4mm tall. Press fits into the end of the extrusion.

- Fully closed cap to cover the entire extrusion, has locating pins to keep it from rotating.
- One rail open cap that's useful to keep access to one rail, also with locating pins.
- Fully open cap (I like using it as feet for whatever is being built)

Modeled to fit the tnutz.com extrusion but should fit most of the other ones.
