Sorry for not answering sooner; I used 0.25" ID / 0.375" OD clear vinyl tubing (available at any hardware store) for the stunt nixies.
No problem at all. Thank you for the reply, I really appreciate it
Maybe a dumb question, but what colour nylon webbing are the non black GB2 fobs? Is it a white or a greyish? I can’t tell from the photo and when I look to buy some, I can find white but not a light grey. I’ve found silver, is that it?
Personally I’ve gone with two white fobs, it’s really difficult to know the proper colour on the screen…it’s either white or gray
What do you use for actually sticking your template to your actual leather holster? Velcro possibly
I used the silver grey that Strapworks offers for my set of fobs:

I just have it wedged in between the two spots where the band connects to the backing; just make sure you make your board a little wide so it will sit snugly inside the holster. The is essentially how the screen-used gizmos for both films were secured. 
The fobs were definitely a light grey. The prototype belt that was on the mannequin with the Super Hero pack at Sony had some white fobs, but all of the screen-used ones appear to be grey. The Venkman belt from the Sony Archives still has a grey fob on it to this day.
Thanks for the answer. I picked up some white and some silver so I can decide when I’m making them.
So you’re starting on a GB2 belt? I look forward to seeing what you come up with. 
I printed my template off last week & your right about it fitting snug in the pouch, last time i had all my gear i used velcro on the back but never liked that idea much
Do you have directions on how to make the GB2 belt?
Where did you get the gb1 snap hooks?
I found the GB1 snap hooks on eBay several years ago; I haven’t been able to source any with the accurate rectangular slot, and last I heard, the manufacturer changed the design to have rounded corners.
I recently made a new set of gizmo and trap holsters for my GB1 and GB2 belts. Although I had been working on my own GB2 gizmo holder template for some time, I opted for Jairus’ great template which more or less matched my own measurements. Check out the other useful templates on his website: JairusWhitley.com
For the GB2 trap holster, I cut the aluminum back plate from 1/16" aluminum, and I used one of CPU64’s v-hooks.
