This is an end cap for a misumi style 30x30 t-slot extrusion.


There are two STL files, one with a hole, one without.
More importantly, there is an openscad script to create your own.
There is a variable at the beginning called "undersize" that you can use to adjust the fit for your printer and extrusions.
It would also be pretty easy to modify it for different sized extrusions.

I'm not sure what the slot geometry is like for other manufacturers, I don't know if it will work for them.

One suggestion: If you chamfer the edges of the bits that go into the extrusion it may be easier to center and tap in into the extrusion.

I made a respin of this and turned it into a filament spool rest part for a 20x20 extrusion. It is for the spool holder that comes with the Cetus 3D printer. You can find it at http://www.thingiverse.com/thing:2073625
