Perfect application for owning a 3d printer:
Saw other cyclists having this hot mudguard on the back of their saddle. Looked it up and it costs about 10$. Since it is just a piece of plastic I asked myself - why not print my own version of it?
There you go! After some iterations I managed to find a design which fits just perfectly into the frame of the bottom side of the saddle. This design totally saves my ass on a rainy day! Since the dimensions of the bike saddles frame are standardized, this mudguard should fit to your bike as well.
Make sure to carefully slide the mudguard into the frame of your saddle. Check out the last picture in the gallery, which shows the bottom side. You will realize that you first need to clip both rods into the provided gaps and then slide the nose of the mudguard into the thin slit of saddle mount. Moving the whole mudguard a little to the front will slightly tilt it upwards, which makes your bike look really hot!
Have Fun saving your ass and share your makes, I would love to see other colors on other bikes!
There are two versions now:
bike_mudguard.stl -> is the original design with a total length of 279mm, which fits perfectly on the printerbed of the prusa i3 mk2 if you position it diagonal
mudguard_short -> is the new and shorter version for all smaller printbeds. With a total length of 250mm it is designed to fit to the print bed of the anet a8.
The total length of the mudguard is 279mm and easily fits on the printbed of my prusa i3 mk2 if I rotate it by 45% to be diagonal.
The height of the flat part is 0.6mm which totally sufficient for this purpose. I printed the mudguard with a layerheight of 0.15mm so I ended up having 4 layers for the thing part.
Adjusting the infill will not make any difference since there is no big volume at all. Having 4 shell layers lead to a 100% solid part.
I was using PLA which performs very well. It is capable of holding off the water... for a couple of times now already. ABS or PETG might be more durable. Would be nice if somebody could give it a try!
