<p>A remix of <a href="https://www.thingiverse.com/ioi671701/designs">IOI671701's</a> <a href="https://www.thingiverse.com/thing:4486659">Hornady Comparator Set Organizer Box</a>.</p><p>This box will hold:</p><ul><li>5 headspace comparator inserts (A, B, C, D, E)</li><li>8 bullet comparator inserts</li><li>1 anvil</li><li>1 spare grub screw (under the anvil)</li><li>1 comparator body</li><li>1 1/16" hex key</li></ul><p>Changes from the original:</p><ul><li>Hornady's basic bullet comparator set now comes with 7 inserts instead of 5. Plus they offer 7 more individual inserts for less common bullet sizes. I enlarged the box to hold 8 inserts.</li><li>Locking tabs on the lid.</li><li>Reference table for the headspace comparator inserts embossed inside the lid. I chose what I guessed were the most popular calibres.</li><li>IOI671701's description and photos mentioned a spot for a spare grub screw under the anvil, but it is not present in the STL files. I added it. But instead of using tape to hold the screw in, I made the hole smaller than the threads. Screw it in.</li><li>Rounded the corner in the recess for the hex key. Without that, the key doesn't fit well.</li><li>Filleted edges.</li><li>Fancy lid graphics. I added the Hornady logo.</li></ul><p>I think the Hornady logo looks mighty fine on there, but if Hornady's lawyers don't like it, I'll delete it. I don't want no trouble, mister. I've also provided a version without the logo, just the name "Hornady Comparator Set".</p><p>This is kind of a work-in-progress. After I printed mine, I tightened up the lid fit a bit more, and that's what's provided here. But haven't reprinted it myself with the tighter fit. Also, I find the components difficult to get a grip on. In the future, I may add some sort of grooves for easier access.</p><h3>Printing Notes</h3><p>The lid should be printed with the top surface down. Some of the fine details of the lettering are very troublesome to get to stick to the bed. I ended up resorting to glue stick, but it leaves an impression in the surface finish. I believe turning on "External perimeters first" in PrusaSlicer (it's an Advanced setting) for the first 1mm of print height might also help.</p>
