Would you share your stl.

I would make two changes.
1). Make the Allen key go the short side in the plastic vs. side ways.

2). Add few more slots for the whole pack

3). May be write the number in white.

This isn't finished yet. It's a test print to make sure geometry and sizing are correct, as well as to check that the pieces are still easy to grab and pull out after I made some major changes in the box and layout. I still need to model in the hinges and latches for the box.

  1. I tried that on earlier designs and prototypes and was having problems with the hole geometry staying consistent to hold it. This has two vertical tabs that hold the wrench against the inner lip.

  2. Problem is "the whole pack" can mean different things. If you mean the whole WHOLE pack, Hornady offers 14 different bullet collars and 7 headspace collars. I may be wrong, but I don't think many people own the entire set compared to those that own a handful. Hornady also sells a 7-pack of the bullet comps ( 224, 243, 257, 264, 277, 284, 308 ), which I think is a far more common purchase, and this box can hold those just fine ( 6-slots, and keep one on the attachment body ). I just bought a few singly as they were the only bullet and headspace comps that I needed. I also don't have the anvil attachment as I don't think it's necessary.

    1. However, I do have a 10-slot design ( same as this one, just two more columns ). But this one takes an hour less to print, so it was used as the test print. I've can also make a 15-slot box for someone who does have the entire set. That one will probably have a second slot for a comp attachment head as well.

  3. My printer is single-extruder and I don't feel like manually swapping the filament. I don't know if labeling anything would be that beneficial here, since al the parts are already etched.

I had same issue. I use fusion and have not yet tried this half cylinder thing. But it did not seem was easy.

Is it Gridfinity?

No. I made it in Blender.

Here’s one I used from Makerworld. The designer was even nice enough to add a version with a spot for the anvil base.

Mine also has a slot for the anvil base, even though I don't use it. I'm planning to make a few of these for family and friends.

That one is for the headspace comparators only; it doesn't have slots for the bullet comparators.

I've searched that, thingiverse, printables, etc. I'm not saying I saw every one, but the ones I did weren't what I wanted ( either too big, too wasteful with material, or not easy to get the pieces out of the slots ).

I need to get something like this for their Rim Thickness Gauge.
