The DryBox from IKEA Samla is designed for an 8mm rod and M5 Push Fits. This DryBox uses an M8 rod that allows the use of 608 bearings for the filament rolls. This way, the only friction is caused by the 4mm PTFE tube that starts from the PushFit and goes all the way to the extruder. If the box is placed on top of an IKEA Lack table, you can use this filament guide. The Taulman Bridge coil was about 18mm in diameter, so a bit of modification with a hole saw was necessary. The PushFit adapter consists of two parts for extra stability. Various sizes of Spool rollers are available and the length of the 8mm rod is 310mm. The product also includes Fusion 360 files.
