Burton snowboard channel insert

A couple years ago I lost the channel inserts on my burton snowboard and now that I have a 3D printer, I decided to print some replacement ones.

Originally they are made of rubber and their purpose is aesthetics only or just to slightly prevent boots from sliding when riding from a chair lift to another one.

I don't know if they fit tight enough not to lose them while riding or if they are durable enough, I'll know that this season!

I don't know why but exporting STL files from Inventor causes me some dimensions issues, so the part's dimensions are:

W: 19.5mm
L: 27mm
H: 6.5mm
