About this 3D model

This is a great way to help reduce filament tension. Using some tweaked printed bearings from emmet's http://www.thingiverse.com/thing:53451, this filament holder should help eliminate friction and tension on your filament, giving you better prints! I modified the bearings to have a smooth inner bore as well as having a 50mm outer diameter. This matches the hole size of the Type A Machine filament spools almost perfectly. Required materials: 5/16" wooden dowel Adhesive foam or similar to serve as a spool block
