This is meant as a boot riser to help with costumes and cosplays where your foot needs to be higher to prevent other portions of the costume dragging on the ground. This is still a work in progress with a few kinks to work out, but figured I'd go ahead and share in case iteration of the design would be beneficial to anyone. For reference, I am using it with a US size 10M shoe.

The larger holes throughout the RiserHeel and RiserToe parts are meant to accept M3 heatset inserts. Originally I used these for magnetic mounting to my own parts, but they can be used for other mounting as well. In addition to M3 hardware, these also include slots meant to be used with 1" Nylon webbing. Even with these straps I still get a bit of unintentional movement of my foot on the risers, so some additional work may be needed to fully secure your foot. A Shoulder bolt is also used to join the RiserHeel and RiserToe sections. See below for details on these additional parts.

This design also uses flexible components to help with traction and shock absorption while walking. Any parts with the prefix "TPU" should be printed in some kind of flexible filament. These flexible parts are meant to be joined to the rigid parts via M3 hardware. The height for these parts may be scaled, but I would not recommend scaling any other parts of directions.

Additional Components:
M3 hardware: M3 x D5 X L4
Shoulder bolt: 1/4 Diameter shoulder, 2-3/4" shoulder length, 10-24 thread
Nylon Flange Locknut: 10-24 thread
1" Nylon webbing
