After my V1 mudguard extension, I invested some time and filament, to create a parametric version with FreeCAD from scratch. So, this is not a remix of the V1.

The V8 model can extend the mudguard by 30 cm, 10 cm at the top, and 20 cm at the bottom. But you can set your length! The model is parametric, just enter your length in the spreadsheet of FreeCAD, export and print it!

The issue with the original front mudguard of the ST2, ST3, ST5 and the ST7 (ST2: the new models with 27,5 inch wheels) is that it is a little too short for rainy road conditions. Without extensions, it is easy to get your shoes and pants wet.

One extension consists of two model parts that can simply be screwed together, mounts and a mudguard extension. It can also be printed without support. Except if you print a mudguard longer than 15 cm, a brim is recommended.

The mounts and the extension are screwed onto the mudguard instead of just being plugged in like the original plastic part. That way, it stays securely in place. The mudguard has already holes at the end which can be used for the screws.

You need the following bolts and nuts to mount one mudguard together and onto the mudguard:

• 6x M3 hexagon nut
• 4x M3 x 20 mm Allen screw
• 2x M3 x 8 mm Allen screw

The nuts can be placed into the brackets with a longer screw, they should not fall out. But I recommend some water-resistant glue to secure the nuts in place.

As mentioned, the model was created with FreeCAD 0.21.1.
