Dry box for 2 spools of filament

To assemble this box you will need:

4pcs 608 bearings (For the new version of the winding rollers, 8pcs 608 bearing is needed.)
2pcs - M8 threaded rods 164 mm long 
6pcs - M3 bolt 30mm long.
The 2pcs screws are used as the rear hinges of the box and the other 4pcs screws are used to mount the closing clips.
 

2pcs - Pneufit Connector PC4-M10
Thread G1/8
Suitable for 2/4mm diameter bovden
Used in Ender printers

A box lid without holes has been added. Designed only for storage of filament in the box. Cannot be used for direct printing from the box.

The box allows you to insert a label from the outside with a description of the materials inserted. (Material type, manufacturer, printing temperatures and other necessary information. The space for inserting the label is really big, so you won't miss any necessary information.

I modified the feed rollers to Royal Farris' design and adjusted their width to accommodate the larger width spools.  With the author's permission, I am adding this modified version of the base between the print profiles. 
All that needs to be done is to print 4pcs filament feed rollers using 8pcs 608 bearings. (The original version only had 4pcs 608 bearings.) The bearings are pressed into the rollers on both sides. The bearings that were originally in the base will be replaced with printed rings to replace the bearings.  If you are already using the dry box and want to improve the filament unwinding, I recommend printing these few parts and simply replacing them. Thanks to Royal Farris for this modification to the design.
