Skull rope pull knob

This is for the pull rope on my attic ladder.

This is actually a remix of a remix. I couldn't load the original .STL file into Tinkercad. CameronD9 did a remix, a keychain. https://www.thingiverse.com/thing:1131743

I loaded it into Tinkercad. I removed the keychain loop. I scaled it up 200%. I put a hole through it at a 20 degree angle. The hole fits standard paracord. Feed paracord through it & tie a knot. The hole is 5mm with a 10mm section at the bottom for the knot.
