Filament Dry box Tube Retainer

For retaining a 25mm tube inside a DIY filament dry box. My box will hold 4 spools of filament and wanted to print directly from the box via Boden tubes. I considered spool edge rollers and the centre tube options and went for the simple option of a 25mm tube running through the centres of the spools. I found a few stl files on Thingyverse, but not quite want I wanted. These have plenty of support and because the pipe goes all the way through the bracket it will be retained. I would encourage you not to use PLA for these brackets. There is one file for counter sunk screw/bolt and another for standard bolts, the holes are 5.5mm in diameter plus one 4.2mm holes. Also added a HD version with more bulk around the tube support. It has the same 4.2mm fixing holes
