Changelog :
25.02.2022 --> check out the great remix of ketonk
for another version of the holder and the ring connector

31.12.2021 --> V4 --> additional holder (long version), magnets on the inside
(both holder versions are compatible with all Ring versions)

13.03.2021 --> V3 --> improved light situation

14.02.2021 --> V2 --> make design simplier and easy to build

It fits perfect for an Dartboard with an diameter of Ø450mm x 50mm (Winmau Blade 5)
A Dart Surround (Catchring) will give additional support so you might not need the magnets in this case.
For the Dimensions of the LED-Ring check the 2nd picture.

For this Dart LED Ring Light you need additional material:

1) Magnets Ø8x3mm to fix it on the Dartboard (optional)
Magnets (or similar products)
2) LED Strip (width doesn't matter: 8, 10 or 12mm are possible)
"for great results choose a colour temperature between 5500k-6500k "Daylight White"
LED Strip (or similar products)
**Power Supply is needed (12V)
3) Superglue to glue the ring parts together and Hotglue to fix the LED strip

The Files you need:

4x HolderV4.stl [long or short, I prefer the short version]
(You can choose how many parts you print, check the picture with the dimensions
for which version you want to go for (HolderV4_short or HolderV4_long)
10x RingV3_10th.stl (For bigger printers 10th of a whole circle)

Optional Files for smaller/bigger printers:
16x RingV3_16th.stl (for smaller printers 16th of a whole circle)
8x RingV3_8th.stl (for bigger printers 8th of a whole circle)
Total cost: ~10€

Mounting Instruction

1) Assembly the Ring with the holders together, without glue.
2) Separate the Holders equally
3) Now start opening 1 Connection of the Ring and Glue it together again, and wait till
the glue cures fully
4) Continue like this till you glued all "Ring-Parts" together
5) Finally glue the holders also to the Ring
6) Glue the magnets of the holder in place
7) Put the LED strip into the ring
8) Hide the connection Cable of the LED strip behind a holder, you might need some
Hot glue to fix it behind one holder
9) Mount it on your Dart Board
10) Ready to go

Additional Notes:
Everything is printable without supports (if you print it in the position as shown in the pictures below).
