High Performance Spool Desiccant Container Holder

Main Features

- Two high airflow and high surface area desiccant container versions for effective moisture absorption for keeping filaments dry . Both having high density open mesh walls and self-centering open spoke ends for improved air circulation throughout the whole desiccant core and spool - High Flow (HF) version with triple internal towers to maximise silica gel surface area while allowing air to reach the silica gel deeper within the container for better efficacy. - High Capacity (HC) version for greater desiccant capacity for long term storage, easier refilling and additional weight. - Performance, strength and print tested container design (test details at the end) - Tested to reduce humidity in a dry box faster than a desiccant container with low surface area. - 2x faster silica gel drying speed with high flow version for faster drying in filament dryers and ovens. - Tested to be capable of maintaining low humidity within a heavy duty resealable bag. - Load tested to 10kg without structural failure, ensuring a durable design. Able to prevent Bambu spool halves from coming apart. - Test fitted in 26 different spools (test fitted spools in “Compatibility List”) - Print tested in a wide range of materials including polycarbonate for high temperature drying, and fiber reinforced filaments for advanced users. - Highly refined and optimised design print profiles for reliable printing and smooth fitting parts for over 50 different design variations - Three core sizes for different inner diameter spools - Standard Core for 50mm - 63mm inner diameter spools for wide compatibility and high airflow. Can also be adapted for 63mm - 80mm inner diameter spools - Large Core for 55mm - 63mm inner diameter spools for maximised desiccant capacity whilst maintaining adequate airflow and compatibility for most spools including Bambu spools. Can also be adapted for 63mm - 80mm inner diameter spools - XL Core for 60mm - 75mm inner diameter spools for spools with a large inner diameter - Silica gel capacities for dry silica gel (wet silica gel will be 20-30% heavier) : - Standard Core for Bambu spools: HF ~52g, HC ~68g - Large Core for Bambu spools: HF ~68g, HC ~88g - XL Core for Sunlu Gen 1 & 2: HF ~75g - Three available mesh sizes for different sizes of intact desiccant beads (damaged beads will need finer mesh size) : - Standard mesh: >2mm - Fine mesh: >1.5mm - Ultra fine mesh: >1mm - Up to 7 desiccant cores can be dried in the AMS 2 Pro, AMS HT or any filament dryer using the drying spool (link) - Different lengths with size markings to provide a secure fit in a wide range of spool sizes from 250g to 1kg spools (test fitted spools in “Compatibility List” and in print profile pictures) - Extra options for alternative add-ons - Hygrometer version for desiccant humidity monitoring - Standard and Large Core adapter for 63mm - 80mm inner diameter spools - Standard Core RFID tags for labelling of spools and AMS RFID reading function - Two sizes of funnels to aid with filling - Alternative locking end ring lengths - Optional opening tool - More updates and features to be added…

Print Guidance

The design and print profiles have been carefully optimized for easy support-free printing. Many hours of work had been spent optimising all the print profiles, and many modifiers are used within the print profiles so please be sure to print using my uploaded 3MF print profiles. Printing from raw STL/CAD files or make changes to the print settings are not recommended. The mesh on the ends of the container won't be visible in 3D model, as it relies on slicer modifiers to generate the mesh. Once the models are sliced using the print profiles, the mesh will appear in Bambu Studio “Preview”. If the design is printed without the yellow modifiers & settings, no mesh will be printed! Please also ensure Bambu Studio is up to date as older versions may causes issues. Would recommend printing the design using Bambu Handy App for easy convenience. Filament type can be changed and the number of copies can be increased within the app. (Please note: Bambu Handy App will rotate the containers when multiple copies are printed. This only affects the high flow containers which will misalign the towers with the bottom mesh. This doesn't affect the function, but will change the appearance slightly. Please use Bambu Studio if you wish to keep the mesh aligned with the body of the container)

For Bambu Studio, you can right click to select all the parts, and use keyboard shortcuts (e.g. CTRL+K) to clone a number of copies before right clicking the plate to arrange. Please avoid manually moving models if possible, as it may mess up the placement of modifiers within each model.

Please always ensure the print bed is cleaned, and filament is dry before starting the print. Poor bed adhesion can result in first layer problems which can lead to print failures. Moisture in filament can cause stringing in the parts and can also cause issues with parts fitting together.

Printing with Bambu Labs filament is recommended for best results. Other filament brands can also be used, but some filament brands may not handle default generic filament profiles, and may result in poor quality prints without filament tuning. If you are having such issues, please tune the filament with appropriate print temperature, volumetric speed, flow dynamics, flow ratio, cooling, etc. Having the correct filament tuning is important, as it can affect the strength, quality and fit of parts. The threads of the design are designed with a loose fit in mind, but filament or printer problems can result in inaccurate threads with imperfections. If there are imperfections on the threads, common reasons are wet filament, or improperly calibrated flow dynamics or flow ratio.

When printing with engineering filaments like ABS, ASA, PC, etc., prints must be done within enclosed chambers. Excess cooling can result in warping or weaker parts. Although basic print testing with the X1C produced adequate results in part strength, taking additional steps can further enhance the strength of the design. Pre-heating the chamber, using chamber heating, or reducing part cooling (reducing fan speed for overhangs or disabling forced cooling for overhangs and bridges) can reduce warping and significantly improve layer adhesion strength of the design.

The 3D model for the design is only optimised for printing with a 0.4mm nozzle. Most fiber reinforced filaments can be printed using a 0.4mm nozzle but some may require a 0.6mm nozzle. Whilst it's possible to adjust the print profiles for a 0.6mm nozzle, the print quality may be reduced due to the lack of optimisation in the 3D model for printing with a 0.6mm or 0.8mm nozzle.

Slicer settings if printing with STLs only

- Import the raw STLs into the choice of slicer. Exclude the STLs for core_mesh , cap_mesh , core_mod and end_mod . All cap and end STLs are the same so only one of each is needed. The main container body STLs are labelled with HF for high flow, and HC for high capacity, followed by the mesh size. - To slice the files, make sure the printer preset is a standard preset for 0.2mm layer height for a 0.4mm nozzle. Other layer heights or nozzle sizes may have issues. - Configure the print settings to be 4 wall loops, 0 top shell layers, 0 bottom shell layers - Depending on which container is being printed, set sparse infill density in print settings: 40% for standard mesh, 55% for fine mesh, or 42% for ultra fine mesh - Then set sparse infill pattern in print settings: triangles for standard and fine mesh containers, or rectilinear for ultra fine mesh - Some additional settings may be needed: “Only one wall on top surfaces” should be disabled, and brim may need to be disabled if on auto.
