Adapter CB09 to Cameo 4

Version 2 is ready - it is interesting for everyone who uses different knives …

The original holder is very nicely made, I love it. Unfortunately, when cutting, it wobbles back and forth like a dog's tail in my Cameo 4. (This is a remix from Ductippi's CB09 adapter ).

I think it's due to a little too much clearance to the retaining clips (about 0.5-0.8mm depending on how tightly I put it together) and the lack of a guide on the back as this makes the knife wobble easier .

That's why I sat down at the weekend and redraw and adapted it to my needs (I can't say whether the guide rails were necessary, but I did them right away).

The dimensions are taken from my CB09 ( unfortunately the Chinese don't always take the dimensions of the cheap parts that precisely - so there is no guarantee that yours will also fit )

The parts are very tight (no desire for tape and wobbling). So a resin print is recommended and the CB09 needs to be pressed into the parts a bit. I also tried my hand at a scale (with a suitable rotary knob) because I don't feel like fumbling with a label on it (forget the numbers on the scale, you can't see them anyway, but they make the STL nicer ;-)

You can use the metal plate from the white adapter that comes with the Cameo 4 so that it is recognized automatically – I think a 14x7x0.5 mm aluminum sheet should also do the trick, but since I don't need the adapter I used the sheet from that.

Please note that these are not original Silhouette accessories, so using them can invalidate the guarantee. Use is at your own risk.

- UPDATE 20. Jan. 2022: Today my second CB09 knife holder arrived. As already feared, they don't take the dimensions very seriously. So I added all the parts with a 0.1mm larger inner diameter.

The old one has a diameter of approx. 13.83 mm, the new one 13.94 mm. but the big ring fits both.

Post-Printing

The metal plate and the ring of the CB09 really only go in very tightly, I went over the corners again before assembly with a dentist's hook (a needle certainly does the job too) to make sure that the corners really did work which are.

A waterproof pen and a steady hand helped to make the scale easier to read.

This might help you with FDM printing: Since well-adjusted FDM printers also have the property of printing the inside diameter a little too small, this setting may help to compensate for this. Unfortunately, we don't have much space for tolerances here and the CB09 should fit as precisely as possible in the adapter.
