Aluminium is also an option, but it has to be at least 0.5mm thick and not polished (which will also cost some money) won't be as smooth as steel and might cause a problem with coffee not sliding down.
Cutting that hole might be kind of a problem as well:| I haven't found a solution to it yet.

It's pretty much your call, steel or ally... "coffee not sliding down aluminium?" ..after having fallen 10 cm down the chute??
The thickness (of the aluminium) should be no problem, bear in mind that the wall thickness of the plastic doser housing (top part, which is fixed to the main body of the grinder) is around 4 mm (if not more, I will measure).
FYG, the -cylindrical shaped- Macap doser is affixed to the main grinder body with two screws, one on each side of the "square coffee hole". At this point, the doser is approx. 4mm thick plastic, perfectly cylindrical. At the part where it is joined with the main body, the cylindrical shape of the doser fits into a corresponding (same diameter) cylindrical "cutout" in the main body of the grinder (otherwise it is impossible to mate a cylindrical side against a flat bodywork: the shapes have to "fit" positive-negative).
So, it is important that the chute be exactly the same OUTER diameter as the doser, otherwise it will not "mate" jointlessly... I think at this point, the situation shold be exactly the same as for any doserless Macap. Please advise...
(Below only FYG - immaterial to doserless Macaps)
Under/below the plastic part of the doser, there is attached the "metal" part of the doser, enclosing the mechanism ("tchack-tchack"). This (aluminium) metallic part has exactly the same (outer) diameter as the plastic part of the doser, and is -at some point below- firmly attached to the grinder main body.
But this is not important for the working purpose of the chute, which will anycase completely supplant the doser, the mechanism of which becomes totally superfluous. There will, probably, remain a "hole" in the main body of the grinder corresponding this precise point, but that will be of no consequence to the fitting or working of the chute, the shape of which will probably to some degree cover that void.
One solution I see to the "square hole" (cutout in the chute) is NOT to make a full 4-sided aperture: the TOP of the square hole can be left out altogether, cutting only a "U" shape from the top of the chute (instead of a full square "hole" within the wall of the chute). Cutting a "U" should be easier than punching out a square hole (punchout from a cylindrical shape!?) AND it has the advantage of leaving some "adjusting play" for adapting to the grinder body. In fact, provided the holes (for the screws) are at exactly the correct lateral distance, the holes could even be vertical "slots", allowing for some "adjustment" as to exactly how "high" the chute be mounted. But indeed, I would leave the holes for the screws up to each participant to do himself, it should be relatively easy with any electrical drill...
You might wish to comment, please read it carefully and with attention, maybe the "doserless" Macap's main body is shaped differently, even though I cannot imagine it would be???
