Bambu spooler stronger and easy filament guide change

Because of the annoying filament ends on bought spools, I was looking for a solution. One is moving the filament to another spool, ensuring the end (or beginning) on the new spool will not be bent. So I went looking for a spooler and found the Bambu version which seemed to be great.

And it is a great design, however, it is rather wobbly. So I went looking for a stronger frame. Found it but to my likings still not strong enough. So to the drawing board.

I redesigned the entire frame. My frame is made from different parts which must be connected by M3 inner hex screws.

Axes I used from STORM DESIGN. They are easier to print and thicker/stronger

Also I put the gears in an enclosure.

Lastly I recently created a filament guide to fit narrower spools (the original one goes about 65cm left to right, way to far to stay between the 2 big discs of the spools).

To make changing the filament guide more easy, I cut the vertical axis of the filament guide in 2.

The lower axis holds the gear which is connected to the frame and is driven by the worm gear.

The upper axis holds (of coarse) the gear with the missing teeth. But beneath the filament guide, I created a part which hooks into the lower gear.

The filament guide is held in place by 2 levers. To remove the filament guide, just open the levers, tilt the filament guide and pull it out. Another filament guide (made for wider or narrower spools) can then be inserted in reverse steps.
