Part of the Filament Swatch System. 

This is a frame of 20 samples displaying infills at different densities (10-30% in steps of 5%).

This frame displays Rectilinear, Grid, Line, and Cubic infill patterns.

The other infill frame is here.

This 3MF works by splitting the model into separate parts and printing each part with different settings, so will only work in Bambu Studio. I have attached the original STL where the blocks are literally filled in panels, so you can play with splitting it into parts and setting different settings for each object if you like.

I wanted to build a system for displaying the BambuLab Swatches and other useful printing samples by hanging them from by reprack style filament storage solution. So as well as this infill frame, I have made a frame for other infill patterns, a frame to hold bambu standard swatches, hooks to hang the frames from reprack style pipe filament storage, and rings to present the frames in way that can be flipped through.

The frames all have small spaces under the tile so that a label can be printed and stuck on. I use Niimbot labels that are 12mmx22mm. I haven't bothered with the Bambu swatches as they all have printing on to let you know what they are, but it's useful with 3rd party tiles and the infills.
