Download, Modify, Remix Design

The parts were modeled in Autodesk Fusion 360 and available to download, modify and remix. The parts can be exported in several file formats - great if you're using a different CAD package.

Material Options

To get the intricate details, we used the ember DLP/SLA resin-based 3D printer from Autodesk.

But you can use an FDM machine with PLA, ABS or other type of filaments which may require a heated bed. PLA prints with minimal warping and doesn't necessary require a heated bed.

Slice Settings

The table below is a general reference for slice settings. Every 3D printer is slightly different, so you might want to use settings you're familiar with.

0.1mm Layer Height
Custom Supports
50/150 mm/s Speeds
1-4.5mm retraction length

about 40 mins on FDM printins

about 3 hours on SLA / DPL printers

Edit ring size

Customize the ring size to fit by measuring the width of your finger. Input these measurments into the sketch for the ring size inside the Fusion 360 project file. The depth of the ring shank is offset by 3mm. You can edit this if you need a thinner or thicker shank.

NFC Slot 

You can edit the position of the NFC slot by moving the sketch. You can edit the slot position if you wish to adjust the thicknes of the ring shoulder.

Ring Head

You can adjust the size and shape of the ring head by editing the attached sketch. We included a circle and a ploygon. You can even project a symbol or logo on the ring head!
