Dehumidifier box for granule bags

Model

Dehumidifier box for granule bags of Calciumchlorid-Dihydrat.

Size about 252 to 142 mm.

Printing instructions

I printed the box with a nozzle of 0.8 mm but 0.4 will also work.

• Use Arachne wall generator.
• Use PETG
• With 0.8 nozzle 2 walls, with 0.4 nozzle 4 walls
•  

To make the bottom watertight:

• Print slower as usual
• Print a bit hotter as usual (+5° C)
• Use a bit higher flow ratio
• Make the bottom solid (no infill) by increasing top and bottom layers until you reach 1.6 mm with these layers.

I used Geeetech PETG for the print with 240° C and with a maximum volumetric speed of 13 mm3/s and used a bit higher flow ratio, 99% instead of 98%, which I use otherwise for this filament. With this settings my box is watertight.

Other recommendations 

Test the bottom for watertightness before you use the box!

I am only the designer, you are the maker and fully responsible to test your print before use :-)

Happy printing and successful dehumidifying!
