eSun PLA Pro 1kg Spool Converter - 29mm Diameter Center Support Rod

Remix of eSun Spool Holder by Luscombe8E (http://www.thingiverse.com/thing:1092175) to have a 29mm diameter hole for the center support rod. My setup used a 27mm diameter PVC pipe for the center support rod so I needed a modified center support rod hole to support that. This works on my eSun 1kg PLA Pro spools.
