This model allows you to position the scraper aligned or centred on the board's slots. When using the model with two push fits on it note that you only need to insert it into one snap for a secure hold, you can use 2 but only one is needed.
Simply push into an existing snap securing the board to the wall or use a multiboard snap piece.
You can also use this on the HSW (Honeycomb storage wall) using the multiboard to honeycomb snap piece.
You can find the scraper here https://makerworld.com/en/models/12702#profileId-12703
I print with 10% infill, 0.2mm layer and 2 walls.
