English: (Spanish at the end)This is a chain guard for some Decathlon bikes (from 2010 onwards). I bought a chain guard from aliexpress (CNR002) but at some point it broke so I made a design by eye based on that one, that means it may not fit perfectly but I printed one and it fits decently (see first picture).The distance dimensions between the screw sockets are:105mm long axis 96mm short axis. The diameter of the outer circle is approximately 187-188mm (I did this by eye based on the photo of my plate so I wouldn't read too much into that parameter).There is a secondary structure that is not very important (it doesn't have the bolts) about 74mm apart. You can see if it looks like the chainring of your bike in the second (My chainring) and third photo (photo from Aliexpress, it is not exactly the same as the one I made but in the dimensions of the screw holes).Printing settings:Infill: I used about 10% I think it's not very important because they don't have that many parts with infill.Supports: NoMaterial: Any (I used PLA)Español:Un protector de cadena (protector de platos) para algunas bicicletas de Decathlon (sobre el 2010).Compré un protector de cadena en aliexpress (CNR002) pero me lo cargué así que hice un diseño a ojo basado en ese, eso significa que puede que no encaje perfectamente pero imprimí uno y encaja aceptablemente (ver primera foto).Las dimensiones de distancia entre los huecos de los tornillos son:105mm eje largo 96mm eje corto. El diametro del circulo exterior es aproximadamente 187-188mm (lo hice a ojo basandome en la foto de mis platos asi que yo no me fijaria demasiado en ese parametro).Hay unas estructuras secundarias que no son muy importante (no llevan tornillos) con una distancia 74mm. Puedes mirar si se parece al plato de tu bici en la segunda foto (Los platos de mi bici) y la tercera foto (Foto de Aliexpress, no es exactamente igual al que yo hice pero si en las dimensiones de los agujeros de los tornillos).Ajustes de impresión:Relleno: Usé un 10% no es muy importante porque no tiene muchas zonas con relleno.Soportes: NoMaterial: Cualquiera (Yo usé PLA)
