Custom Fitted Wristband

I designed this wristband specifically to fit my wrist. It's 220mm (2.2in) in diameter. Unlike many of the official Apple Watch bands on the market, this one does not contain any sizing holes. If you'd like to 3D print my design, but have different size wrist, you will have to modify the CAD files. Not too way, it's not too difficult! I designed the band with user paramters – So it's [relatively] easily adjust the overall length of each band. I put together a "Layer by Layer" tutorial on how to do this.

3D Printing Flexible Filaments

If you haven't 3D printed flexible filaments yet, don't worry! We have a dedicated guide on how to 3D print with ninjaflex. Click the green button below to launch the guide. Below are some basic settings for reference.

• 235/240C Extruder Temperature
• Non-heated bed – blue painters tape or PrintInZ surface
• Heated bed – 50/65C
• 30mm/s default printing speed
• 60mm/s movement speed
• 50% first layer speed
• 1mm retraction distrance 
• 30mm/s retraction speed

3D Printing 2-color filaments

You can acheieve a "dual extruded" 2-color print with a single extruder 3D printer by swapping out the filament during the print. By using the "pause" feature, the 3D printer will rest the extruder, allowing you to change the filament mid-print. If your 3D printer doesn't have this feature, you can set your slicer to print only a portion of the model. In this project, I told my slicer [Simplify3D] to print only 1mm of the band. Then, I used the "start/stop" layer modifcation feature to start the printer at 1mm. For a step by step tutorial on how to achieve this in Simplify3D, check out our 3D Hangouts video.
