The Engwe M20 is a great Moped-Style E-Bike, but the seat was a little low for my liking. After seeing some demand for a solution in a few groups, I decided to make a 3D printed riser for it. This is the 3rd version, and it provides an additional 2.75" inches of seat height. The print is designed to use TPU for durability and conformity, and requires the addition of M6 coupling nuts and studs to lengthen the stock mounting hardware.

Print Settings
Print using 95A or 98A TPU. For my prints, I used 15-20% infill with 7-8 walls. At these settings, it will use almost an entire roll of the linked filament. This may be overkill, as much of the weight of the seat is supported by the studs, but I would rather have it be durable and only have to print it once. The default orientations should provide the best overall visual appearance when finished.
