Better DryBox for filament dessicant Spool Holder

A better Dry box with Desiccant holder, Label, PTFE connector for Australian Cereal Box

This is a reworking from scratch of 3d print designs to make a Dry Box from readily available cereal box in Australia. I wanted to make a print with no support required that contained a round hygrometer, silica gel container, Label, outlet for PTFE tube without taking the filament out of the box and using minimal effort. The cost of the box with ball bearings, filament and cereal box was only $11.50 AUD .. about $8 USD.

I will add a video on step by step instructions. 

I found I was getting failed prints due to stringing and blobs forming, and took some time to realise it was because of the humid atmosphere. I found the models available did not suit me and used more than double the filament and double the time to print, in addition to having wasted support.

There are 4 plates to help with printing in the optimal manner. 

1. Printed in white PETG, The main body and rollers etc.
2. To be printed in TPU for best effect
3. Labels .. pick one you like if you want a label
4. silca gel container .. I usually print in clear PETG.

If you want to print from the container you only need make one hole with a 4mm drill bit (as in the pictures).  Then add the adapters for guiding the filament and connecting to the back on the 3d printer. No other holes or adjustment to the cereal box should be necessary. The silica gel container will friction fit into the round flap. Just twist the top on the gel container and then push down into the flap.

The spool holder will hold normal size 1kg rolls, and half width spools (as in the image above, add the “middle TPU” part on the roller if using the half width rolls.)

PARTS

1. Food Storage Container from Big W
2. Ball Bearings 608 22x7x8 Bunnings or on line for ½ cost
3. Filament PETG/PLA and (optional TPU)
4. Round Hygrometer

TOOLS REQUIRED

1. 4mm drill bit and drill if you want to connect with PTFE tube

This may fit US cereal box because they seem to be the same dimensions.

Updated to change desiccant holder for a better fit and airflow during drying. More updates are coming including a multi-roll filament drybox with filament holder and easy access to roll out the filament from the box.

It took a while to make this and if you like please boost, contribute, give constructive feedback or suggestions etc. ..
