Bincho-zumi for Bambu Lab X1C, P1P and LDO Voron Trident

I designed Bincho-zumi. it is an activated carbon filter for the Bambu Lab X1, ARC-P1P and LDO Trident 300. It's minimalist hexagonal shaped in design with a zen garden-inspired base. 

Items to print and BOM

3. 4020 axial fan 24V or 5V depending on how you power it. Look for dual ball bearings, 8.9cfm and 7000rpm version. Amazon Aliexpress
4. M3x25mm or M2x22mm for mounting fan - 2 or 4pcs
5. Activated carbon (min size 4mm non acidic)
6. tea filter bags
7. 6x3mm magnets 10pcs Amazon

1. v28_Bincho-zumi v28_bincho base LDO trident.stl
2. v28_Bincho-zumi v28_bincho fan body LDO.stl
3.  M4x6mm & M4 T-Nut - 1set

Bambu Lab X1 and ARC-P1P:

1. v28_Bincho-zumi v28_bincho base X1.stl
2. v28_Bincho-zumi v28_bincho fan body X1.stl

Instructions

1. All printed parts should be printed high temp filament ie PETG, ASA or ABS. Do not use PLA or PLA+ it will be a limpy mess when using in a heated chamber. 
2. No supports are needed for all stl. 
3. The fan body is the more difficult to print due to vertical hexagonal shape. So print it separately and slower from the rest of the parts to reduce chance of failure. 
4. Print all the parts from the Common stl.
5. Print the specific parts for your printer 
6. Install the magnets in correct orientations. The holes are designed for the 6x3mm magnets to be press-fitted. If it is too loose, use some glue. The magnets are slightly inset into the holes. This is to prevent the magnets clashing on each other while put together. 
7. Unhook the wires from it retainer so that the 4020 fan can be properly installed. 
8. The fan is suppose to suck air from the carbon box. So the direction of the fan installation is for the wind direction to be be pointing downwards. (see image) 
9. Fill a teabag filter with activated carbon and place it inside the carbon box. clip the cover on and you are ready to use it. 
10. Please note that all new fans need time to run it. So if its a BNIB fan, run the fan for at least 30 minutes. 

Installation / Positioning

LDO Trident - The base plate can be secured with the single M4x6+ T-nut. There are a lot of space available on the Trident, so it is up to you where you want to install it in. I design it to be placed against the back panel. 

BambuLab X1 - please install the magnets for the base and under the fan body. The base has space to allow the L-shaped extrusion on the X1 enclosure base. Use the single M3x6 screw secure the base. Please do not over tighten the screw and strip the plastic enclosure. 

Wiring

If you are build a LDO Trident, there is already a point for the connecting the nevermore. So connecting it is simple with the 2 pin fans.

Powering up the Bincho-zumi fan is the tricky part for Bambu Lab X1C. Something has got to give or be sliced together with. There is only 2 fan ports; one is connect to the chamber fan, the other to the Aux fan on the left side of the printer. You will need a JST 1.25 connector if you want to use either of these ports (or a splitter cable) 

To wire 2 pin fan to a 4 pin port, u will need to use the connect the black cable to GND and red cable to Power or PWN. If you are connecting it to the printer, make sure you are using a 24V fan (don't say I did not warn you). I am still trying to get a proper reply from Bambu Lab regarding wiring, but the reply was non-commit as I don't think they want users open the back panel and mess with the controller board for mods. 

So do it at your own discretion and if you mess up, don't come karen/kevin on me. 

I use 5V fans and run a separate 5V power supply. 

Till date (Oct 2022) all my designs are free to download and use. There is no Pateron or OnlyTechFan (hahaha). If you like my designs and want to contribute to my coffee addiction and help fund the filaments I need for prototyping, a donation of $5-$10 to Ko-fi or paypal.me will be greatly appreciated. Thank you.

Caveat

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