Dreame L40S Pro Ultra / Ultra AE - Dust Bin

As a replacement for my trusty Xiaomi Mi Vacuum, I chose a Dreame L40S Pro Ultra.
I tried to print two other dustbin models, but none of them were perfectly compatible with my L40S Pro Ultra.
I also took the opportunity to simplify the emptying of the dustbin with a magnetic sliding hatch.

This Dust Bin is compatible with : 

Dreame L40S Pro Ultra

Dreame L40 Ultra AE

(Maybe other, could be updated if tested)

Adaptation for other Vaccum :

Mova S20 Ultra

Dreame L10S Pro Ultra Heat

Filtration is done with a simple filter I still had from the Xiaomi Mi Vacuum, centered on the suction port of the base.
It’s this model: https://fr.aliexpress.com/item/1005009330958975.html?spm=a2g0o.order_list.order_list_main.29.79025e5bAdGzux&gatewayAdapt=glo2fra

I also added an O-ring at the junction between the dustbin and the suction base (Tor 2.62mm / Inner Diameter 32.99mm: https://www.theoringstore.com/store/index.php?main_page=product_info&cPath=367_23_24&products_id=1148), a model I already had in stock.

But models with an inner diameter of 33mm and a 2.60mm tor will also be compatible :)

The attachment of the connection plate and its spacer on the dustbin is done with two screws and two nuts:
- 2 countersunk M3 screws, minimum length 10mm
- 2 M3 nuts

Yes, you’ll probably struggle a little to put the nuts in place, but I assure you it can be done :)
The easiest way is to go through the 33mm hole by placing the nut on your finger. The screw must not stick out at the back in order to place the nut. Once the nut is aligned with the hole, just push the screw in and tighten it.

For the magnetic hatch, you’ll need 4 magnets with a diameter of 8mm and thickness of 2mm.
The magnets are glued onto the sliding plate, and then you just need to glue the small finishing plate on top of the magnets.
(It has already happened to me that glued magnets came loose. With this solution, the magnets won’t move anymore :) )

I think that’s everything.
On my side, I’ve only tested this model with the Dreame L40S Pro Ultra.
I could update the compatibility with other vacuums if that information is provided.

I hope this model will suit you :)
