Designed to attach with zip ties;
Works on my 27.5 MTB with 2.1 tires but will probably works up to 2.4 just fine.
Initially printed with PCTG, but it started to crack along the layer lines after about 6 month. Printed Nylon afterwards, and now it is much stronger.
I added a longer one (MudGuardLong.stl) as this was requested, but did not try to print that one myself yet.
The author marked this model as their own original creation.
