Pegasus Galaxy ring for Martins 80cm Stargate

WARNING IF YOU PRINT THIS YOU ARE BASICALLY BETA TESTING FOR ME!
i have no time to testprint all those new pieces i made! they should work and fit if everything is calibrated but no guarantee!
 

Edit 9/8/2025: Realised the step file was missing some components, i uploaded the full step with all components!

Smoothed out the front of the rings so no glyphs are visible
a 0.2mm thick layer will allow light to shine through from the back to stealthily hide the glyphs unless needed
also trimmed the ring to fit the 80cm stargate and scaled it down to 740 OD  and 670 ID as well as a thickness of 3mm to accommodate the diffusors i created for this

 

wire suited for your use case! make sure it can take the current that all leds would draw if they where at full brightness and white!
used this Led strip,  it needs to be a max 3mm wide,  max 1.5mm thick strip!

i had ordered a 5v 5m strip, i suggest getting a 12v 5m strip unless you have a power supply capable of around 10amps at 5v 
you would also need 27 neopixels (matching the voltage of your strips for the ring) 

you have to probably add power to both ends of the strip, or else the end of a strip could discolor!
I would suggest getting the 12v version as the 5v version needs an insane power supply with so many leds!
the whole strip is super fragile, the solder pads as well so be careful!  1x 5m strip was enough for me to work with, cut in half, one half lining the inside one the outside diameter of my led carrier, then insert the diffusors to hold the led strip in place and well diffuse the light!
 

all 9 ring segments

9x dovetails to connect the ring segments together
36x Accent pieces to glue into the front once everything is assembled
36x Diffusor printed in an opaque color

i suggest printing the ring pieces in two color so that the front 2-3 layers are the color you need, and the rest be a super dark color preferably black!
The pieces are designed to have one 0.2mm layer of filament where the light shines through, so choose a filament for the first layers that lets light through! i suggest a test print 0.2mm tall to check for translucency when the leds are white behind it!

assemble the ring, put the led strips inside the ring both facing inward towards the glyph area
put the diffusors in to hold the strips in place, as well as diffuse the light
rout the cables out one of the openings, make sure to ad power to both ends of the strip!
you should have 10 wires in the end ( or 6 if you wire the power from the both ends together )

then comes the tedious part, you have to map all leds to the corresponding glyphs!
i used an Arduino code to cycle through all lights on a button click, and output the current index, and then noted down the beginning index and ending index for each glyph,  do that times two for the other strip as well

my Arduino code is by far not the best for this! but it at least works and you could use it as a base to do the rest, i haven't had time to finish it


Also! i suggest using the other remix pieces that make the gate LED ready for the chevrons and to have more space behind the ring for stuff like an esp32 etc!

This current version is untested!! use it at your own risk!
your printer has to be calibrated for skew, shrinkage and accuracy! one only 0.2mm deviation can cause the whole ring to be to big or to small to fit in martins base gate!
i have successfully printed the previous version of those parts which consisted of all 36 glyphs standalone, needing to get clipped together and glued to the led carriers! for this release i have integrated carrier and 4 glyphs together into one unit to make it easier to print and assemble!

if you notice anything that could be changed, would help making it easiest feel free to tell me and i try to integrate those things into future releases if i got the time!
right now however i am to busy with irl stuff so fixes might take a while to be pushed out!


 

Scaled and cut down, smoothed outside with a 0.2mm solid layer to hide the glyphs when leds are off
