Okay, the FIRST prop I ever built for any costume way back in the day was the belt gizmo. (LINK) WOW! Almost 5 years ago this month!
It was built from one of Nick-a-Tron’s amazing resin boards and it’s served me well but since Spongeface started doing his “real” PCB replicas I’ve been wanting to upgrade. I bought a board in his first run 2 years ago (also in September) and it’s been on my “to do” list since.
At the time I said I’d like to look at a better way to make the nixie-shelf than was currently available and that 3D printing could be an option but there was a problem:
-
It was relatively new back then to print in 3D and therefore more expensive.
-
I knew nothing about building 3D models (I’m a 2D CAD guy)
-
I didn’t have any real details about the nixie shelf size etc. (I asked a couple of times for measurements, never got any firm information)
So… a few years on, I have taught myself (enough) 3D CAD, I’ve taken “best guess” measurements from photos of the real Sanyo board and this is what I’ve come up with:
It’s alright I guess… then when I started researching printing in 3D I found out there’s more I could do, so I went back to the drawing board and came up with this:
Added error box detail
Thinned out the legs/bracket
Offset the grommet thickness
Increased the “resolution” of the curves.
Okay, nobody wants to see sketches, so I went ahead and found a company to print it for me.
Voilà:
What’s next?
I’ll probably use this print on my Mk 2 Gizmo as it’s printed and I’ve paid for it already etc but if I were to do it again I’d probably make a few minor tweaks:
-
Add the wire holes in the Error box so it’s ready to go!
-
Tweak the 3 details on the Error box (I think the middle arm of the “E” is too wide)
-
Add a support “rib” to the underside of the bracket to add strength
-
Make the holes in the grommets pass all the way through
Also, the company I used to print it for me charge by “swept volume” so regardless of how much media is used, the price is the same if I pint within the volume of the bracket. What this means is that if I were to design and draw the plug for the end of the daughter board wire and add it to a spru on the underside of the bracket I could get that printed too at no extra charge.
Now all I have to do is start soldering on all the components to the motherboard, sheesh.
