Tension Nut with Flange for 3/4" PVC Pipe

Keep things in place on a 3/4" PVC pipe. I use these to keep my spools from wandering all over during a print job. I started with gsterley's Solidoodle Spool Holder Mk2, but now use them with my own. They keep a tight grip on the pipe but flex to accommodate variances in pipe diameter.

This version has a flange to keep spools with large center holes in place. See Thing 116872 for the standard tension nut. I use these to reliably print my cameras on pinholeprinted.com.

This version has an arm to feed the filament: http://www.thingiverse.com/thing:737197
