Bento mini for Bambu Lab X1C P1P and Voron V0.2

UPDATE 8 Apr2024

I believe in working with local small businesses when selecting regional vendors. Unlike established companies that are good at managing logistics and sales, small businesses or new start-ups are still learning the ropes, and sometimes make mistakes. Everyone makes mistakes, but it's important to make things right and work towards improvement. 

Bento mini is now available with Australia vendor JC-3D. They have improved their ops & logistics. There will also be no more pre-orders to prevent late fulfilment. 

Vendors:

The US vendor for Bento mini - A collaboration between ThrutheFrame and Voxelpla to offer a complete set (printed in pet-g) with acid-free activated carbon included. For more information, please visit Voxelpla Store.

Introduction

Back in September 2022, I designed the BentoBox air scrubber for the X1C and enclosed P1P (such as ARC) to be used for printing ABS. This helps to reduce the fumes and VOCs build up within the enclosure. When I decided to build the Voron V0.2, I needed a BentoBox with a smaller form factor. Not an easy project due to the limited space within the V0,2 chamber. It has to be small, powerful and visually pleasing. 

Meet Bento mini. Small in size, powerful, and looks like a little bento for kids. The front dimension is the same as an iPhone 10. It uses a strong 6028 blower fan to push air thru the carbon pellets. There are 4 mounting holes where brackets can be customized for different enclosed printers. 

What Does the Bento mini do?

It is an activated carbon air scrubber housed within an enclosed printer. By cycling air thru activated carbon pellets within the chamber, it helps to reduce fumes and VOCs when printing filaments such as ABS, ASA and Nylon.  This method of filtering air within an enclosure is called multi-pass which results in better filtration. 

What Advantages does it have over others?

• Bento mini uses a more powerful fan (6028 vs 5015) which allows it to push air thru the pellets more efficiently. 
• When installed, it collects the hot air from the top and exhausts it at the bottom.  This allows proper air convection current which helps maintain a steady enclosure temperature.
• it is cuter.
