Yet another 5lb reel holder

This was made to simplify 5lb reel changes. There are (4) 19mm diameter bearings with 6mm hole that fit into the flange covers. The rods hold the bearings in a good position to feed the filament into the extruder. Using a t-slot nut and a bolt, the rods fasten tight to the 30mm x 30mm aluminum extrusions.
