Spengler / 84 Neutrona wand 28 segment bargraph upgrade made easier

Hi All,

I did the Frutto Technologies (now also sold by GPStar) bargraph upgrade on my 84 wand a while back and whilst it looked amazing, the process of cutting up the clear part left a lot to be desired and the optional printed part wasn't a great fit either.

Having got a 3D printer during the Black Friday sale at Bambu, I set about remaking the inner frame of the Neutrona wand, but designed to house the new bargraph, making it a much easier fit (you still need to do a small amount of soldering).

This is what I came up with:

This is the second version I've published, as I wanted to make the light hats look more realistic for home printing and let more light through, so redesigned those too, to look more like cliplites.

The clear one looks like this printed with PETG translucent

Assembled you get this (before putting the bargraph in)

You can see I made the vent cover a separate item, as some people have removed the cover when upgrading to make it more accurate, I quite like the defused / can't drop anything in there look personally :)

This is what it now looks like all lit up

For those that haven't seen the bargraph mod in action, here it is with my v1 holder


and a tiny clip of the v2 where I printed the slo-blo light in red translucent PLA, you can see how much brighter the LED's now glow;

Hopefully for anyone considering this mod, this makes it easier for you, both my wands now have the mod and doing it the second time over with this was a tonne simpler!

Very cool! Does this make it more accurate to the movie or is this more of a fancy upgrade?

I think the fact that it adds a real bargraph, rather than 5 LEDS behind a screen makes it more realistic, but wouldn’t have thought the bouncing animation etc.. would be from the films, I’ll have to watch again with a keener eye on that part of the wands
