Creality Space Pi PLUS - Multi Function Lever

First of all : I would like to thanks the several users that helped me create this model. As I do not personally own the dual spool version of this dryer, you helped me a lot at different levels with your inputs! So thanks a lot Ghoulzy ; Haydock ; dtsn ; OrbitMechanic ; @user_3409396465 ; daliyenigun ; Hobbes82

Special thanks to @ajiata for your decisive help and the pictures!!!

IMPORTANT NOTE : this design is made for the “2 spool” version of the Creality Space Pi PLUS

If you own the “single spool” version of the Creality Space Pi have a look at this model: https://makerworld.com/en/models/1493133-creality-space-pi-multi-function-lever#profileId-1561110

02/09/2025 : Version 2 added following request to increase the height of the handle from 1,8mm to 3mm to better match the slot of the lid. If you feel this change is not suitable please let me know by message.

I was not completely satisfied of my filament dryer Creality Space Pi so I created this upgrade to improve its functions and ergonomic.

(Pictures bellow shows the single spool version, but the functions are the same for the the dual spool version)

It is a 4 in 1 multi-function lever :

1. It strongly hold the PTFE tube in place and prevent it from being pushed inside the dryer while printing. 
2. It can create a small opening of the lid when you dry your filament, to allow moisture to exit while keeping the heat inside
3. It can lock the lid closed, so it won't open accidentally if you grab the dryer by the lid when you need to move it, and it secures it if you want to store the spool inside for a long time
4. The funnel on the inside really ease the filament insertion

The 4 positions of the lever are indexed (they stay in place each quarter of turn), I thought it was a nice addition. 

There is also a possibility to use a M10 connector if you absolutely need to secure the PTFE tube (see the special print profiles options). Just screw by hand the connector :

On the “Classic” version : the base of the PTFE tube housing has a “thread” to secure the tube, just push the PTFE tube to the bottom and screw it if needed!

You only need a small piece of filament of your choice to install it (approximately 50mm long) : no screws needed, no threads that could fail or create a mess while printing! It also makes the removal also very easy : just pull on it!

The flat washer is adding smoothness (I suggest PETG for even less friction) and protects the paint of the dryer casing

The assembly should be straightforward, but here are the instructions :

You can print the lever in PLA for a better look, but keep in mind the other parts are exposed to the temperature of the dryer! So except the lever, please consider a print in PETG, ASA, ABS…
