This is a remix/inspired by the official Bambu Lab Scraper Grip.

I first printed the official one but then Multiboard released their new multibin series and I wanted to try it out.

So I made this model. The original idea was to adapt this to make it a multibin inset, but it was early on when the documentation wasn't up and I felt it was a bit hard to understand existing models.
In the end I made the model fit a inset.

This model is based on multibin 1x1 with 1.5H.
I used 1x1 with 1.5H multibin shell, a multibin inset and then this model.
You can probably skip the inset but it will be a loose fit, possibly that you can increase the scale by 101-102% and make it work.
