The Ultimate DryBox Filament Feeding System

thingiverse

The Ultimate DryBox Filament Feeding System I examined a multitude of filament feeding systems and storage systems, but none suited my needs. After numerous trials and adjustments, this system is functioning effectively, and I've decided to share it. If you choose to build this, please post photos of your "Ultimate Drybox." I'd love to see the finished product. Airtight Clear Plastic Cover I employed a clear plastic cover to enclose the drybox. The cover is secured with tape to prevent moisture from entering and compromising the filament's quality. Shelf Brackets / Rod Holder To conserve time and filament, I utilized shelf brackets to support the rod, accompanied by a 3D printed rod holder. This configuration enables easy access to the filament for changes or maintenance. Filament Feeder A previously created filament feeder bolt and nut were used to extract the filament from the drybox. A custom-made nut was added to secure the feeder to the wall, ensuring stability during operation. Humidity Control A humidity meter holder was designed to provide easy access to the battery compartment and facilitate accurate readings. A rechargeable dehumidifier is used to maintain optimal humidity levels within the drybox. Spool Hubs Adapters for spools were created to accommodate standard skateboard bearings, ensuring a secure fit and efficient filament flow. Shelf Brackets / Rod Holder (continued) To simplify changes or replacements of filaments, shelf brackets can be placed in the middle, breaking up the rack into multiple segments. This configuration also accommodates longer steel rods if needed. Bearings - 8mm x 22mm x 7mm These bearings are used for the spool hubs and are available online through various retailers. Filament Feeder (continued) A previously designed filament feeder bolt and nut were employed to extract the filament from the drybox. A custom-made nut was added to secure the feeder to the wall, ensuring stability during operation. Frequently Asked Questions Q: Can you create a custom-sized spool hub? A: Yes, I can design a custom spool hub for you. Please provide the inner size in mm to the hundredth (xx.xx mm). Q: What bearings do you recommend? A: The bearings used are 8mm x 22mm x 7mm and are available online through various retailers. Q: Can you use this system with AIO 500g spools? A: Yes, these spool hubs work well with AIO 500g spools. However, please note that they may overspool occasionally, which is not a significant issue. Q: How much do the bearings weigh? A: The bearings for a set of two 500g spool hubs weigh approximately 9 grams, while those for a set of two 1kg spool hubs weigh around 12 grams.
