The Ducati Desert X is missing a plug for the frame - there are just two holes from the tubular frame above the footpegs. I did not like that - especially as on the right side water would just accumulate when the bike is on the kick stand.

The plug offers a lip going around the frame tube. Printed with TPU filament - 3 layers and 30% infill on textured build plate on a mk3s. 

 installed mine with a bit of grease. I also made a normal plug without the lip - this could be uploaded as well.

This model includes the STEP file if you want to make changes - I thought about integrating the logo but I like my bike clean and with as little logos as possible.
