This smart filament samples are designed with an integrated NFC chip for storing information about the filament.
Features
Thin walls test (3, 2, 1.5, 1mm)
Material type display (Currently PLA, PETG, TPU, ASA, ABS and a blank version are available)
Hole for a key ring
Thickness/shine through test (0.2, 0.4, 0.6, 0.8, 1.0, 1.2mm)
Round holes (2, 3, 4, 5mm diameter)
Layer visibility test
Integrated NFC chip for storing information about the filament
Recommended print settings
Layer Height: 0.2mm
Sparse infill pattern: Cubic
Sparse infill density: 25%
The sum of top and bottom shell layers should be at least 6
No supports needed
Printing and Assembly
You will need some NFC chips in the right size. For enough storage space, I do recommend those NFC chips (affiliate link)
Optionally, you can add some sort of key chain in the top right corner (I recommend this chain (affiliate link))
When preparing the print, make sure to insert a pause before the space for the NFC chip (when printing at 0.2mm layer height as recommended, the pause should be right before layer 12)
When the printer pauses, insert an NFC tag
After printing, you can optionally add some sort of key chain in the top right corner of the sample
Use the app “NFCTools” to write your filament data to the NFC chip (add your parameters or just a link to the website)
When having many samples, you might want to also consider to print my box for them (linked at the top of the description)
