Possibly the best DryBox yet!

I've combined four top models and modified each to create an almost ideal DryBox:

1. Base: I removed the silica compartment, as it wasn't convenient to refill, so there was no need to keep it. The base fits the DryBox perfectly, with no play. The fins ensure the spool stays on the rollers and doesn’t hop off.
2. Lid: The original auxiliary lid was replaced with this printed one, which includes a hole for a PC4-M10 fitting. The lid size was adjusted from the original model to achieve a precise fit.
3. Silica Gel Container: I repositioned the container to attach it to the DryBox lid, simplifying silica gel replacement and increasing the container's capacity. It can now hold 130 grams of silica gel. For a cleaner look, adding support for external overhangs is optional but not necessary.
4. PTFE Fitting Plug: This handy accessory seals the DryBox when the fitting isn’t in use. It's best to print this plug in TPU, but if TPU isn’t available, PETG works well too (I used PETG, and it provides a good seal).

All necessary parts can be printed at once. I recommend using PETG, especially transparent, but PLA also works well.

In the 3mf file settings, I’ve reduced the printing speed for outer surfaces and overhangs to enhance quality.

The DryBox is compact, lightweight and requires no drilling, as the printed lid includes a hole for fitting installation.

Using a funnel can make it easier to fill the silica gel container with desiccant. If you have no any suitable funnel around you can use something like this https://makerworld.com/en/models/718359#profileId-649195 , however it was not designed specifically for this silica gel container, but can be used without any problem.

To create this excellent DryBox, in addition to the printed parts, you may need the following components:

• Vtopmart cereal box 4L you can find here.
• Bearing 608zz for rolls (4 pieces minimum) you can find here.
• Double-sided tape to attach the silica gel container and hygrometer securely in place  you can find here.
• Really good Xiaomi thermometer/hygrometer with bluetooth you can find here.
• Silica gel. The good indicator desiccant (orange) you can find here. The colorless desiccant - here. 
• Fitting PC4-M10 - here.
• PTFE tube (ID2.5 OD4 or ID3 OD4) - here.

You may find it useful, budget and environmental friendly to use dummy CR2032 battery in the humidity sensor.  

And do not to forget to put inside this DryBox a roll of a good filament from JAYO (SUNLU sub brand). The JAYO filament for the best price (EU warehouse) you can find here.

Happy drying and enjoy high-quality printing!

P.S. If you are looking for the solution to reduce 3D printer noise, have a look on soundproof cabinet design, crafted from IKEA furniture. This cabinet reduces printer noise and ensures impressive 36.5 dB(A) at just 1 meter away. Detailed instruction how to build it you may find here
