After printing a few Omni Modular Display Cases, I've noticed some issues that required tinkering to fix. So I threw together some very basic adapters to make my Omni as awesome as it should be. Here are the files I've created / issues I've fixed so far:
1) The sides bow outward at larger sizes, which can cause properly cut shelves to become unstable and possibly fall. I made braces for the front and back to pull the sides inward. The back one fits the existing slots. The front one are just pressure fitted around the LED sticky-outy-bits and fit under acrylic shelves. If you use transparent filament, they're nearly invisible from the sides and barely noticeable from the front. My display cases are all 430mm, so that's the size I designed these for; that said, based on what I've seen, I don't think they're really needed for smaller sizes.
Both of these print in 2 pieces. The front brace snaps together with a peg and hole, but I recommend reinforcing with superglue. The back one requires one of the same small screws used to assemble the Omni.
2) My display cases are mounted such that there's no benefit to using 1/8" acrylic for the bottoms, so I designed a printable shelf for the bottom instead. Since I have only made 430mm wide units, that's the size of this shelf; it should be pretty simple to use a % adjustment to make it fit other sizes. I also made "wing" shelves for the rounded corners so you can store small minis in that space. bottom shelf prints in 2 pieces with an overlap to help support them. It's plenty stable, and does not need to be glued together.
3) Since one of my Omnis needs to store 400ish small (1" base) minis, I made extender shelves to make use of the 3/4" of empty space between each side of the acrylic shelves and the acrylic side windows. These snap nicely into the channels for the shelves, and have no effect on the fit of the acrylic shelves other than to make them slide in snugly instead of loose. When printed in transparent filament, they are nearly indistinguishable from regular acrylic from the front and sides (the view from the top and bottom will depend on your printer settings, infill%, etc.). They are 6.5mm thick, and the existing shelf sits on top of the support, so a standard 5mm acrylic shelf will be almost perfectly level with them.
PLEASE NOTE: THERE ARE NO OMNI FILES OR FILES REMIXED FROM OMNI FILES IN THIS BUNDLE. Some things should go without saying, but we live in a world where lawyers exist, so let me be clear, I don't own the Omni Modular Display Case concept, files, or license. That's why I'm releasing these files for free (well, that and I don't think I'm good enough at this stuff yet to charge for my work). All files are 100% my own, built from scratch, which is why they're not very attractive, just functional. If someone from Omni/Fantasy Designs wants to steal these and make them better and release them to the Kickstarter backers, I think that would be amazing and give full permission to do so. Alternately, if someone with more talent than I wishes to play around with these and make them look better/work better/do anything better, I welcome it and give permission to do so.
If you have any other quality of life issues with your Omni that you want me to play around with, or just suggestions for how to improve these files, please leave a comment.
