This is made out of tpu and alot of color options as well! Carrying case feet for the Olympia SM3. Designed as a two piece replacement that fits very firmly and doesn't require any glue. Installation: - Very easy to install, just place the ?P1? foot in the case first, it will hold itself generally. Then press the ?P2? foot into the slot on ?P1? while supporting the back side. - If your feet seem to be slightly loose for whatever reason, you can add glue into the slot prior to inserting ?P2?. Even if the glue doesn't chemically bond, it can help create a mechanical lock with the layer lines on both pieces. My personal case doesn't have any glue and has no issue with the feet staying in.
