Dual Spool Drying Box Pro

Additional notes: To ensure successful reproduction (meeting usage requirements without wasting filament), please read the following carefully first:

1 The spool holder parts involving the air duct are best printed with high-temperature resistant materials such as ABS. Enable support for different materials to reduce post-processing If conditions are really limited, you can first print the PTC part of the model to check the difficulty of removing supports before printing the air duct model, as the air duct model is relatively large

2 The casing can be printed with PETG, if the usual drying temperature does not exceed 60 degrees

3 If there is a demand for high-temperature drying, choose a higher temperature-resistant material to print the casing according to your drying temperature, which will be relatively safer and more reliable. Similarly, the accessory selection will also have slight changes. The default configuration is only suitable for 60 degrees, not exceeding 65 degrees. Higher temperatures will require increasing PTC power, increasing fan speed or changing fan size, and increasing the KSD temperature protection limit. However, after modification, it will not be suitable for low-temperature drying, please consider it carefully

4 For non-standard sized filament spools, please measure whether the size is appropriate before printing. Designed dimensions: 75mm > spool width > 55mm

5 Recommended printers: X2D, H series Others have not been tested, and printing success is not guaranteed

Design background and some thoughts: First, thanks to Theebob for bringing a series of high-value drying boxes, which not only have practicality but also add a sense of beauty. Although rice buckets are good and practical, they always feel a bit lacking. As 3D printer enthusiasts, 3D printing is not just about the present, but also about poetry and distant places. Two years ago, I designed a 3D printed drying box. Due to my limited vision and inexperience at the time, many things were considered quite narrowly, and the equipment limitations were not very friendly for high-temperature resistant and large model printing, so I gave up. The subsequent rice bucket drying box series was also designed out of laziness, not wanting to drill holes. Before making this model initially, I originally planned to use the Theebob medicine box solution, and the prototype was already made. The effect was roughly as follows (If anyone is interested or doesn't mind drilling holes, you can click the image below to jump to the model drawings)

However, during the production process, I really couldn't stand the agony of drilling holes, and it was easy to mess up if not careful, so I gave up. Finally, I chose a dual-spool, fully 3D printed solution. Everything went smoothly. Combining previous manufacturing experience, this nearly compact and perfect dual-spool drying box was finally completed

The entire model assembly is very simple. Accessories are listed at the end and can be purchased accordingly. Please see below for some points to note during installation:

If anything is still unclear, you can watch the detailed assembly video:

The wiring diagram can refer to previous drying box models. They are almost identical. It's too simple, so it won't be repeated here
