Bowden Speed Loader - more power & filament guide

Boost MeSupport me <3

 

I've been using the Filament Speed Loader by @MrFlippant for quite some time now. I find the idea and its execution in this size truly impressive. It generally works very well, but sometimes it simply lacks sufficient power. Therefore, I've been thinking about how to get more power out of it. More on that below.

 

I also tried the remix by @Shaki, which guides the filament on one side. However, since it can sometimes slip slightly with imprecise use and the filament then grinds down, I attached an additional guide to better control the filament.

 

More about the motor: This type of motors comes in different speeds and voltages. I opted for a 6V 300rpm motor. This can easily be run with a 9V battery, as it's not used continuously for extended periods and therefore doesn't get hot. Furthermore, these motors are usually designed for a wider voltage range, such as 3-9V or 6-12V.

With this motor, I achieve almost the same speed as with the 12V 500rpm motor, but with significantly more power. And it works perfectly.

 

The direction of rotation can also be easily changed by swapping the poles of the motor. In my opinion, it should always rotate to the right.

I also added a small arrow to the lever arm. Additionally, I added two arrows to the 3MF file in the slicer, which were then printed directly onto the file in dual color.

 

I've also made a version for motors that are slightly shorter. 
And a version where you can fix the axle with a nail or a rod. Drill the holes accordingly. I did it so that the nail is fixed by the lever arm and runs freely in the suspensions.
