Description

IMPORTANT

Please download the "BentoBoxV2 2023XXXX.3mf" project 3mf file and “BentoBox20 User Guide 2023XXXX.pdf” Descriptions, BOM and build instructions are in there. I try my level best to make it as comprehensive as possible.
Use only ACID-FREE activated carbon pellets.
I do my best to double-check and test the print profiles I created. Therefore, I will only take feedback and update for those profiles. I cannot vouch for profiles uploaded by others, so please do due diligence.
Please use the print profile that I upload. Print profiles created by others may not have the most updated parts.

UPDATE 8 APR 2024

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.

BentoBox V2 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.

UPDATE 16 FEB 2024

The grills on the CMAG are slicer-generated. If you are using Bambu Slicer or Orca Slicer. click slice and the settings will generate the grill holes. If you are using Prusa Slicer, there is a version for Prusa Slicer in the download. If you are using Cura, please read the user manual for the slicer setting to produce the grill holes.

JPN

「KOTOBUKI パウーバイオ」はテストしました、酸は含まれていません
This seller in Japan was recommended by a user it has a PH of 9.8.

The HEPA filters:

BentoBox uses the same HEPA filter as iLife vacuum robots. It is 80mmx40mmx15mm you can get it on Amazon or Aliexpress

INTRODUCTION

BentoBox is an air scrubber that sits inside the X1C or enclosed P1P. It removes VOCs and fumes in the air within the printer. Mainly used for printing ABS, ASA, Nylon, and other high VOCs filaments. If you are still unsure if you need an air scrubber, there are numerous write-ups and discussions online on which you can do due diligence.

BentoBox can also be used for other printers. Voron, Vzbot, Enclosed Prusa or Ender 3, your hamster cage, etc

BentoBox V2.0 can be run:

standalone with a separate 5V power source (5V fans),
connect to the printer's 24V PSU (24V fans)
or piggyback on the chamber fan with a cable splitter. (24V fan)

Please download the user guide for BOM and how to install BentoBox V2.0

I know some people may be disappointed that version 2.0 does not incorporate 5015 blower fans. Below is the reason why.

Using either 5015 (push) or 4020 (pull) makes very little difference because both are relatively low-pressure fans. What makes a difference in performance is the unobstructed distance of the fan to the carbon pellets.

I notice remixes of BentoBox where 5015 fans push air through the HEPA filter followed by the carbon pellets. If you imagine the blower fan is waves and the HEPA filter is the wave breaker on the beach. Once waves hit the breaker, a lot of initial force is lost. There will be very little air movement through the carbon pellets. On the other hand, BentoBox pulls air by creating a low-pressure system directly below the carbon pellets. In my opinion, it is a more efficient system.

Do not use Noctua fans. It does not have enough static pressure to pull air through the carbon pellets. You can get the 4020 fans from Aliexpress here: 4020 24V GDSTime 9.0cfm 7000rpm

Redesigned the base (fan duct Voron_Trident.stl) to be used on my Voron Trident. It can fit both 250 and 300. Will require 2 sets of M3x8mm + M3 T-nut. Wire it to one of the pwm fan port and bam you have a HEPA and activated carbon filter. For Bambu Lab printers, please use “fan duct Bambulan.stl”. Everything else is the same.

Dimension of BentoBox V2

There are requests for me to show the dimensions of BentoBox V2 to be able to visualise in different enclosures. They are H=215.6mm D=52.8mm L=112.8mm.

BentoBox V2 in other printer Enclosures

While the BentoBox was originally designed for Bambu Lab printers and subsequently Voron Trident, I hope to make it fit on most enclosed printers ie Creality K1 series, Qidi, Prusa Enclosure, etc. Hence, I will need the community's help as I will not be able to have access to all the different make and models. As always, BentoBox stl will be free for the community, with no club membership, no Patreons, no paid wall, etc.

Some have requested I add a switch to the design. But there are so many different types and shapes of switches. Therefore, I have added the step file of the BentoBox fan_case_duct.step which you can edit to add a switch or mod it.

I printed the design in PLA for a fitting test and then PETG for the final prototype. If you are using ABS or ASA, please print the test piece to check for dimension accuracy and if there is a need to do X and Y compensation. 14mmx36mmx10mm (LxBxH)

To date, my designs are free to download and use. There is no Patreon or OnlyFan (hahaha). If you like what I designed and want to contribute to my coffee addiction, software subscription and filaments I need for prototyping, a donation of $5-$10 to Ko-fi or paypal.me will be greatly appreciated.

Caveat

As with all my designs, it may and may not work for you. So print and install at your discretion.

finished the bento. use 2 40x28 server case fans with an external PWM controller. these fans running at full speed are ludicrous for the amount of air they move. Maximum air volume: 23.78 CFM per fan. great addition to the printer! I tried to use the wireless power for the unit, but with the fans I used, it could not keep up with the requirements, so I ran the wires out the back, and mounted the own controller on the outside. I may design a mount to place the controller on the top right of the case, where the vent hole is already. but. that’s after the holidays.

The designer has replied

@thrutheframe

Glad you like it.

@tcr268

have you thought about doing a top pick-up to mirror the aux fan? the aux fan blows across the model, and the bento box would suck away from the model. that would create a flow around the enclosure.

@m.tokiha

quick question, what controller did you use for the fans?

@user_4166718201

Prints perfekt with ABS. I had to scale it to 100,6% and everything fits perfectly. The 24V power came direktly from the PSU, the red cable lugs are mine. Because I'm very lazy and don't want to press a switch every time, I connected it to a Shelly. Home Assistant now switches on the Shelly when printing starts and after printing has ended/cancelled it waits 10 minutes and then switches off the bentobox. After several hours of ABS printing I can say it works perfectly. I can work in the same room without the smell of ABS

@f.frency97

very nice idea to use a Shelly! I was trying to figure out how to automate it because I often start prints remotely from work while I leave the printer idle at home, I just ordered a Shelly to copy you :)

@Oruyai

I'm new to Shelly, but can you mention how to tie in the automatic venting when printing starts?

@user_4166718201

Replying to @Oruyai :

Shelly can't do it directly. I use "Home Assistant" and add the printer and Shelly to it. It registers when the printer starts and then controls the Shelly. If you don't know "Home Assistant" it's hard to explain.

wired it directly to the empty 24v rail with a switch. love it

@devin.d.ford

Do you have a link for that rear wire cover? i've been looking for a good solution to cover the wires and ensure they never get caught up or interfere with anything. Love the idea of hard wiring it!

This is freaking awesome. reminds me of my favourite Asian cake dessert called Kueh Lapis.

@kstudioca

I got this BentoBox v2 from a vendor, since sourcing those individual hardware products is costing more with shipping cost. Just tip I want to share, after testing the air pressure and tunneling. I found out the 4 unused fan holes are feeding back pressure. I add small square electrical tape up those 4 holes to seal the vacuum pressure. Now it's more effective at the top, sucking air in.

Printed in Bambulab ABS and came out very nice. Thanks so much for your work with this design. I used two 5V Delta fans with an external controller, Clean Carbon 24 coco granular and the HEPA filters from Aliexpress.

@Woswasi

Fantastic design! Added two TPU-sealings between the fan case, carbon and HEPA. I have also designed a version of the base with JST connector and switch as well as cable routing and made it available on Makerworld

A very nice design, good documentation and overall great additional idea to reduce the health hazards of VOCs/Particles emitted by 3D printing, especially when combined with as many other methods as possible (room HEPA filter, open windows, fans, negative pressure venting, ideally a separate room for printing, air quality monitoring) as recommended by recent studies. Going to run this off the 5V 1.5A USB port inside the P1S printer enclosure, to avoid any warranty issues. A wirelessly powered remix version exists, but it seems to require a lot of trial and error, challenge sourcing exact parts, to get a economical/durable/reliable solution, depending on your country or the 5V/12V/24V version, YMMV. To the original designer, would love if the mechanical design allowed for swapping the HEPA filter with the carbon layer box's position (Perhaps a V3? :) ). Could be very useful when using dustier carbon. Many home air filters have carbon first followed by hepa. Would give 5 stars if it were not for that limitation. At the moment, heavily washing the carbon before use, to ensure not dirtying/dusting up the printer enclosure when filtering the air. Side note, careful, if like me, you want to color the text, while avoiding purging-a-lot and decide to rotate the models horizontally (also because you also only have a textured plate and want smooth fitting between parts), make sure you master bridging with your filament first, as you may like me, end up getting portions of the bridging that initially does not fuse together as well as hoped or even sagging. Will poke back this comment with my final results. Thanks for sharing this with the community Cheers

Which 5V fans do you use? Maybe you can show some pictures of cables going from USB to the Bento Box?

@SirSliceaLot

Replying to @bomas_ulz :

@bomas_ulz, I'm personally using the P1S 5V 1.5A internal USB plug, connected with a standard USB A cable (spliced off/carefully checked with a volt meter, prior to installation), going to a DC-DC voltage booster, connected to WINNSINN 24V fans amazon.ca/dp/B08R9HHYF7 (from the wireless Bento Box remix), not 5V fans. If that's still interesting, I can share that.

Replying to @SirSliceaLot :

Yeah maybe 5V fans from Aliexpress then directly to USB without converter as an option for me. Thanks. Do you use a switch to turn the fans on and off? Wondering if you can share 2-3 photos of your cable management through the printer.
