&nbsp;The RIO is the tallest of the bunch at 63.20mm (2.49"). &nbsp;There are thousands of manufacturers with hundreds of different shell sizes in the 2 ¾" spec so this will affect how many you can get in the M19A1 Ammo Can. &nbsp;So, by design, the trays can be mixed and matched depending upon your shell sizes.</p><p>The trays are are divided up into 2 types:</p><ul><li>“A” Trays (2 per layer - bottom layers)<ul><li>Holds 18 Shells per Tray + 2 in the gaps<ul><li>There are two gaps in the middle where the trays come together where you can drop 2 extra shells in.</li></ul></li></ul></li><li>“B” Trays (2 per layer - top or bottom layers)<ul><li>Holds 16 Shells Max (dependent upon shell length)</li><li>The “B” trays are 25mm high so you can lay a shell on it's side and it will still be under the edge allowing you to stack other trays on top.</li></ul></li><li>“C” Trays (2 per layer - top or bottom layers)<ul><li>Holds 32 shells max (dependent upon shell length)</li><li>The “C” tray is almost double the height of a “B” tray. &nbsp;Whereas 2 “B” Trays stacked on top of each other are 50mm, one “B” tray is 44mm.</li><li><strong>It's always best to use 1 layer of “C” trays over 2 layers of “B” trays.</strong></li></ul></li></ul><p>I did not have any 3" shotshells to test to see how much I could get in, but here is a rough idea of how many shells will fit:</p><ul><li>Shotshell ≤ 60mm (2.36")<ul><li>2 Layers of “A” Trays (80 Shells)</li><li>2 Layers of “B” Trays <strong>OR</strong> 1 Layer of “C” trays (24 - 32 Shells)&nbsp;</li></ul></li><li>Shotshell &gt; 60mm (2.36") &lt; 70mm (2.75") &nbsp;- estimated<ul><li>2 Layers of “A” trays (76 Shells)</li><li>1 layer of “B” Trays (12 - 16 Shells)</li></ul></li><li>Shotshell &gt; 70mm (2.75") &lt; 88.9mm(3.5") estimated<ul><li>2 Layers of “A” trays (76 Shells)</li></ul></li></ul><p>Ultimately, you'll have to find the best combination for you!</p><p>I've created print files using Generic PLA and PETG and uploaded the model and project files as well. &nbsp;You also do not need any supports! &nbsp;However, the trays do take some time to print. &nbsp;I tried to reduce that time by cutting down on layer size and width, but I found 2mm is the lowest I could go on the base and the circular shell holders without sacrificing integrity and strength. &nbsp;However, you will find that it is well worth it in the end.</p><p>I hope this can be useful for any fellow shotgun owners out there. &nbsp; Also, if you have any issues just shoot me a message. &nbsp;Thanks!</p>
