About this 3D model

Bambu Lab P1 / X1 Series Modular Bentobox Aux Fan (4/10/2023) Designed a modular second aux fan / bentobox for Bambu Lab printers. Assuming a lot of people will upgrade their P1P to the P1S, they will most likely have 2 aux fans now and this could be a good use for the 2nd one! This is separate from my other model ( https://makerworld.com/en/models/23644 ) as this is meant for users that plan on using the printer in a both enclosed or open environment. Use the dual aux when printing PLA or filaments that need cooling in a non-enclosed setting. Switch over to the bentobox when printing enclosed with filaments that can release unpleasant or harmful odors. The bentobox will recirculate the air, passing it through the filters and ideally removing any odors. Contents Updates Files Additional Parts Printing Information Assembly Wiring Options The X1 and P1 Version are different! This is to account for the Lidar clearance. This will only fit on the right side of the printer! You cannot mirror to work on the left, where the original fan goes, as the frame rails are are different heights ( among other things). Future Update (8/15/2023) Working on an update that will mount the fan to the side panel. Now that P1 users have that option, it will be a faster print, save filament and save space if the fan base is no longer need. See “Test” folder, currently waiting on the new panels to verify fitment - 8/25/2023 Update 7/28/23 Finished the design for the upgraded fan ducts that provide airflow to the back, middle, and front of the build plate https://makerworld.com/en/models/23661 Update 7/25/23 Added multiple wiring instructions. Using fan_1 port to power the aux. Control via Bambu Studios Using fan_1 port to power the aux. Control via Gcode. Keeping the fan_1 port open for the chamber temp fan, wiring 2nd aux to the 1st aux fan. Control via normal way.

Please use PETG, ASA, PLA+ , etc. I used Polylite Pro PLA+ Set your K calibration and adjust setting based on your filament Quality Please see build plate file. Support Please see build plate file. Other Bed adhesion - use brim if you're having adhesion issues, its already configured in the print file so please go over the settings first. * To remove the support from the fan top , I just used pliers and pulled the support out which was pretty easy. Sometimes some of the support stuck but it was easy to clean up with a small knife. The supports on the 2 larger tabs on the fan casing should looked at after the supports are removed, just make sure it's clean on the bottom side since these tabs are what hold it tight against the fan stand. Assembly Remove the fan from casing, remove the sticker over the wiring and redirect the wiring as shown below. Don't put the fan in the printed case yet. Glue in the 24 magnets 3 on the stand 6 on the carbon box 8 on the HEPA box 4 on the HEPA cover 1 on the back plate Place the fan into the new casing, make sure the fan is centered by using the alignment poles Attach the back plate using re-using the 3 screws that originally held the fan into the casing. Tighten the screws 90% of the way making sure the backplate can still move a little. Slide the upper assembly onto the fan stand, same way as the OEM aux fan and use the 2 longer screws that come with the aux fan to tighten the case against the stand. Then make sure the back plate is squared up and tighten the 3 screws the remainder of the way. MOVE THE BUILD PLATE ALL THE WAY DOWN FOR THE NEXT STEPS The stand connects to the floor via lining up the L shape cutout with the L shape extrusion on the floor. There is also a caution sticker and under that sticker is a hole that we will use to screw the stand to the floor. I re-used 1 of the 2 shorter screws that came with the aux fan. Assemble the carbon box, HEPA box, HEPA cover. Rotate filter cover around ( the protrusion gets in the way of the bentobox) or use on the the below models https://makerworld.com/en/models/23650#profileId-22261 Bentobox To use the bentobox, slide the assembly onto the fan casing. The top of the HEPA filter cover needs to overcome the protrusion on the frame so it takes a little bit of force to push into place. Then use 2 M3
