Each sample is 85x54x4.5mm or roughly the size of a credit card. 
Each sample will use ~14g of filament.

The large rectangle on each sample is a small piece (Insert.stl) printed standing and then glued onto the larger part. It allows you to get a better idea of how the material looks in both directions so to speak.

The 6 squares are 0.5 to 3.0mm thick in 0.5mm increments to give a better idea of light penetration. Ideally use enough top and bottom layers to ensure these are printed solid.

The indents at the top indicate the type of material - You can use them as you want or skip them entirely. I use 1 for PLA, 2 for PETG, 3 for TPU and 4 for PA.

Making your own sample cards:

OpenSCAD
The OpenSCAD file is included with the download, this is probably the fastest and easiest way to make these. All credit for making these available for OpenSCAD goes to Knochi / mail@knochi.de

1. Load the OpenSCAD file
2. Change the options on line 2 through 11, ie. the brand, name and type of filament and number of notches at the top
3. Click Render (F6) and wait a moment till it is done
4. Click Export as STL (F7)

Fusion 360
The included 3MF file can be imported in Fusion 360.
A short tutorial on how to edit the text in Fusion 360 is available here: [https://www.youtube.com/watch?v=wBGgSfdIGmE](https://www.youtube.com/watch?v=wBGgSfdIGmE)

OnShape
The sample cards are available on OnShape. Thanks to A Monkey Butler for making these available.

Blender
You can also use Blender, thanks to T0biasCZe for this!

Storage boxes:
There's a few different solutions included for storing these.
• Box Large for 32 samples with Lid and Clamp (fits eg. Prusa MK3)
• Box Small for 24 samples with Lid and Clamp (fits eg. Prusa Mini, 176mm)
• Double Box for 64 samples with Lid and Clamp (fits eg. Prusa MK3)
• WallBox Single for 24 samples
• WallBox Double for 48 samples

The WallBoxes use a mount so they can easily be taken off the wall so you can carry it around and then put it back on the wall later.

3D printing settings

I've printed the samples at 0.2mm with rectilinear infill but the standing inserts without infill. You can print them any way you like but I would recommend to keep the settings as consistent as possible across the line. Use a bit of glue to attach the Insert to the sample card.
Ideally use sequential printing to avoid banding on the inlay or do them as separate prints.
