Same as ysaye's model except I changed the base to half-pitch/half-sized blocks, which fits normal grifdinity (100% compatibility with normal grids and compontents) but can also be placed at half-positions.  The base was cut off a bin I generated using Gridfinity Rebuilt.  That one's MIT license, which is compatible with ysaye's CC-BY-SA so I went with CC-BY-SA licensing.

From original:
Wanted a way to fit more spare plastic scraper blades into a gridfinity 1x1. Not stackable but can be remixed to adjust the heights!

Tested using Sunlu PETG on a Bambu Labs P1S
