Filament Dry Print Storage System (FDPSS) V2.0

The objective of this project was to develop an affordable filament storage system that enhances the functionality of existing DIY solutions. This system is designed to be fully 3D-printable without requiring supports and can be easily assembled without the use of screws. There is also no need to damage the box by drilling holes into it. Assembly is quick and intuitive, relying on sliding or snapping mechanisms. While most of the components do not require adhesives, the new lid mechanism benefits from a small amount of superglue for optimal performance. Alternative glue-free designs were explored but proved unnecessarily complex. By accepting minimal gluing and sanding, the system prioritizes operational convenience and time efficiency, offering significant practical benefits.

With careful sourcing of materials, the production cost per storage box remains low. Key improvements include the box's versatility—it can be repurposed for other uses when no longer needed for filament storage. The design allows for direct printing within the box, with a TPU gasket sealing the filament outlet to prevent moisture ingress during operation. Additionally, there is no need to rewind the filament back into the box after printing. The filament can simply be inserted through the lid opening, and the box can be securely sealed using the gasket on the PTFE tube.

#####CHANGELOG IN VERSION 2.0:#####

• complete redesign of the filament outlet for fast & smooth operation considering printing as well as storage
• replaced the wooden dowels with pla ones to overcome a tolerance issue with the wooden dowels that shrink quite a lot over time
• complete revision of the printing guide and manual
• added real pictures of the actual box
• uploaded all necessary step files making it easier to modify and remix the storage system
• updated all links and added amazon.us links

#####CHANGELOG IN VERSION 1.1:#####

• changed the secondary lid design to completely print without supports
• changed the inner diameter of the rollers for easier assembly
• updated the assembly manual according to the changes
