&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 M2A1 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 3 types:</p><ul><li>A set of “A” trays (A1/A2 - top layer only)<ul><li>A1 - Holds 28 Shells</li><li>A2 - Holds 24 Shells</li><li>The “A” trays are recessed in a bit further from the edges of the can compared to the “B” trays. &nbsp;<ul><li>This is to account for the wide lip on the inside of the ammo can lid (see pics above) that can actually prevent the lid from closing. &nbsp;By recessing them in a bit it will allow the shells to avoid the lip and utilize all of the height inside the can. &nbsp;Although, at the cost of fitting 13 less shells than the “B” trays.</li></ul></li></ul></li><li>A set of “B” trays (B1/B2 per layer - bottom layers)<ul><li>B1 - Holds 35 Shells</li><li>B2 - Holds 29 Shells&nbsp;</li><li>There is a gap in the middle where the trays come together where you can drop an extra shell in.</li></ul></li><li>A set of “C” trays (C1/C2 per layer - top or bottom layers)<ul><li>C1 - Holds 16 Shells Max (dependent upon shell length)</li><li>C2 - Holds 14 Shells Max (dependent upon shell length)</li><li>The “C” 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><li>Use the “C” trays when you cannot use the “A” trays. &nbsp;In this scenario, you'll have space for two layers of “B” trays but not enough space to stand the shells in the “A” trays (see estimates below).</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>1 Layer of “A” Trays (52 Shells)</li><li>2 Layers of “B” trays (130 Shells)</li><li>60mm shell height is about as high as you can go with the 3 layers of the A1/A2 and B1/B2 tray combos. &nbsp;As you get closer to 60mm the cover will still close but it may push down a bit on the shells.</li></ul></li><li>Shotshell &gt; 60mm (2.36") &nbsp;and ≤ 76.2mm (3")<ul><li>2 Layers of “B” trays (130 Shells)</li><li>1-2 Layers of “C” trays (26-60 Shells max)</li></ul></li><li>Shotshell ≥ 76.2mm (3") - estimated<ul><li>2 Layers of “B” trays (130 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 then just shoot me a message. &nbsp;Thanks!</p>
