AM8 Aluminium Extrusion Cap

thingiverse

A cap which you can put over your 2040 aluminium extrusions! Designed to snap in (might need to hit it when inserting), it provides both an aesthetic improvement for the end points of the aluminium extrusions, and also serves as a safety upgrade, so you don't cut yourself on those sharp edges. Print it in orientation as shown in the STL, in other words, upright. You will need to use a bit of supports for the clips. I have also included the Blender file in case you want to edit it further.
