Pipe Stool Leg Glide

I needed to extend some stool legs to fit a non-standard size bar so whipped up these glides to fit into the standard 1/2" EMT pipe I used to do it.

The 8.3-deg glide angle was set to match my barstools, but it should work through customizer for angles between 0 and 20+ deg without issue.

Here's a link to the 90-degree flat remix, since that is such a common need: http://www.thingiverse.com/thing:865392
