About this model

There are plenty of sketches online to make your own MTB mudguard. But why go to all the trouble of tracing, cutting, and punching holes? This model is designed to be printed at 0.28mm (or 0.3mm) and is exactly 3 layers thick which provides strength while still remaining flexible. There are versions with and without the Specialized logo. I recommend color changes for the last logo layer. UPDATE 8/16/2017: Version 2 is updated geometry after attaching the prototype to my bike. UPDATE 9/23/2017: I created a "wider" version for people with fatter tires than my 2.3" tires. NOTE: If you would like a version with your favorite logo, just let me know and I will make one for you. INSTALLATION: Here is a video on how to install on your bike:
