Neon bracelets using Glow in the Dark TPU

I found this great new filament "EONO 3D Print Glow in the Dark TPU" and I could use the same settings I used for the "SainSmart white". They look even better as this filament is see-thru which makes the LED even brighter. The 4 colors of the wristbands are super vibrant in UV light.

Only downside is that the colors from the WS2812 are now shifted in whitepoint depending on the base color of the filament.

From Fail to Glow: Fixing TPU 95A and making an LED wristband

I set out to make a glowing, sound-reactive wristband — but my first try with TPU 95A was a total fail.  

After some help from the BambuLab forum, I fixed my filament settings and finally got amazing results!  

For this second batch of LED wristbands, I’m using fully pre-assembled PCB boards and custom LED strips, all packed tightly into a 3D-printed TPU shell. The design is compact, requires no extra fasteners, and charges via micro-USB.  

With the push of a button, you can switch between fixed color modes and enjoy the light show.

Just finished the 2nd generation of the LED bracelet. I used a new filament this time and it was hard to get the settings right. I used a 95A TPU and it was generating a lot of strings. luckily with the help of the BambuLab forum I was able to fine tune the flow and retract parameter to make a nearly perfect print
