3D Printed Belt Gizmo Build (Pic Heavy)

Hi All,

Hi Everyone,

As we approach this year’s Halloween, I’ve decided to get back into improving my current outfit. I have a Children’s hospital visit coming up with some of the local guys here in Brisbane. And I’ve never really liked my existing belt gizmo build (mostly the bad paint job I did on it and the fake nixies), it was a temp build until I could get around to converting my real 808D over. But now, given the scarcity of the 808D’s I cant bring myself to pull my working one apart.

My hope was that I would be able to pick up one of Ecto Labs awesome Belt Gizmo replicas instead, but unfortunately they haven’t been in stock every time I checked across the year. So onto another temporary belt gizmo build, but this time with a better printer and some more effort to get things to look more real (at a glance for the general public).

This was a fun quick project and I thought it came out OK, and I thought the approach I took with the nixies is worth sharing.

I found this project https://makerworld.com/en/models/1801194-belt-gizmo-with-hostler-and-daughter-board#profileId-1920786 where a fellow had worked out a way to project the circuit traces onto the what seems to be a version of the original Mr Kiou model that I note is still available on Thingiverse (Ghostbusters - Belt Gizmo with daughter board by mr_kiou - Thingiverse)

And that is where my journey began this time.

I didn’t want to follow the complete maker world model, I just wanted the mainboard with circuit trace projection.

So I joined the board back up and painted the parts so that I ended up with this painted model.

Which mid print looked like this

And after a long time came out like this

I ended up chopping up parts of the main board to mock up a daughterboard.

I also modified the nixe holder to move the error box down a bit more like the real deal.

But my biggest issue with my last build was the Nixes, just not looking like real ones. So I ended up putting some extra effort into these on this build.

In summary I designed an internal nixie insert that I could print out of black and clear PETG G. I also found some cheap acyrlic test tubes at the local $2 stores that were the right diameter for the nixie glass lens and cut them down.

To get them all the same size, I 3d printed up a jig to mark them and then sand the height down to a finished eight.

I then drilled a small hole in the base of each which I could feed a cheap battery powered string of LED lights in.

On initial tets sI wasnt happy with teh colour of the leds, so to make them more orange I painted a thing coat of nail polish on each (orange for the numbers, red for the error box)

A quick test (In the end wasnt happy with the digit size and make a smaller version)

Added some small red wires to better mock up the look.

Now bringing it all together…

Comparision to my old one.

And final look..

I think it looks better than my older one, and hopefuully its strong enough to deal with real world knocks etc. But it was a fun build and thought it turned out good enough to share with others for ideas if you cant get your hands on the real/replica boards.

Genius all the way around!

Thanks for the complement, wasnt sure how this build would be received.

It just needs to see me through until Ecto Labs starts making more kits again and I manage to get my hands on one.
