@MiklosKiszely_486882 How did you put the inserts into the 4040 profile? (edited)
Does anyone have a step file for the cookie cutter?
Funktionieren sehr gut, schon 12 Sets gedrückt, Griff-PLA weiß, Form-PETG transparent lebensmittelecht
Is the winder axle correct? Shouldn't it be a herring bone design and not a straight spur gear? (edited)

@brettr6_589719 It's fixed now
@BrandonRaineri Sorry Brandon, you were absolutely right!
It was my fault, I uploaded the wrong file.
But as mentioned before, it's corrected...
I'm really sorry about the circumstances (I really wanted to publish before the weekend, that's how mistakes happen :( )
Hello everyone!
I had fun devising, planning and realizing a purely mechanical spool winder.
Originally I just wanted to do something for myself so that I could fill the Bambu Lab spools properly and easily (because they were constantly "out of stock").
However, since the release I see that it is obviously a "problem" that also many others are having, not just BBL users.
Different requirements quickly come together, such as spool widths of less than 40 mm to 100 mm, spool sizes of 250 g - 3000 g, possibly 1.75 & 2.85 mm filament.
I always thought I was the only one with this little problem because I couldn't find any models with filament guides. (printable only, without electronics)
Why hasn't anyone done this before? :)
For this reason - and because I was already thinking about improvements - I draw a completely new machine with a tool changer for different widths and diameters with better adjustment options.
You should be able to print a basic machine and only the options you need, e.g. 1.75mm filament on a 60mm (inner) wide spool (diameter doesn't matter), then you just print this attachment to the basic machine.
If you want to use a width of 80mm, you only have to print the tool attachment and just change this part. (which ensures a different gear ratio & linear movement range).
It should be possible to change the attachments within seconds without tools, so to speak plug & play.
Got some cool ideas.
Well, whatever... but that's going to take a while.
@MiklosKiszely_486882 nobody did it before because it's a crazy amount of work. ;) Thanks a ton. Sent a coffee your way.
Small suggestion for the next version. Rather than round (with key) and hex for the axles, consider the attached geometry. Square or octagonal for connection to gears or shafts and round only for the bearings. Printed as shown, I think in general you'll end up with a) no supports, b) mostly cleaner prints since there's very minimal overhangs < 45 degrees, and c) less chance of warping since more material will be in contact with the build plate.
@BlindMaker Good morning from Switzerland!
Great recommendation, thank you, I'll definitely consider it!
