Drawers without supports: 45-degree slots.
The only issue I can think of is gravity. The case will bow while your drawers will slide down as your rails are mini ramps not like tongue/groove. I’ve experienced this w my kids plastic toy chest. Great empty, but shifts with objects inside.
Yes and no... I mean yes the drawers will sit a touch low as there is a small air gap on both sides, but I accounting for that with a slight air gab between the drawer and the bottom of the box. Also they can only slide so low as the ramps are in opposing directions on each side.
As someone else pointed out these ramps will also try to push the box sides outward if you have too heavy of stuff in the drawers, but as I'm only putting light stuff in them this shouldn't be an issue for me.
“The word you’re looking for is “tolerance” not “Air gap” and yes, there needs to be a tolerance between the two surfaces. But two angled faces against each other will constantly fight each other bc of gravity. The weight of the drawer itself will pull it down - indefinitely.
Unless you add additional supports and materials and cuts. Then it becomes cost-prohibitive.
What I'm trying to say is that the drawers will only drop so far because of the small distance between the drawer and box wall.
Yes, gravity will still be trying to pull it further down, but it can't move further down unless the drawer or the box are pushed out of shape. This shouldn't be an issue for me because I don't intend to put very much in the way of heavy stuff in these drawers. Beyond that there will be horizontal walls on the outside of these lined up boxes which will prevent (to an extent) the walls from being able to bulge.
In general this is probably a terrible idea for large and/or heavy drawers/objects. But for small, light storage this should work just fine.
You’re right, i have no idea what your putting in there nor the scale of this. It could be a 8”x8” desktop trinket box. Best of luck. Keep pushing the boundaries.
Life is weird sometimes. I try my best to communicate well with stuff like this... part of my job is tech support and I'm so aware of people giving minimal information for me to try to help solve their problem so I usually end up adding more details when I try to talk about something to others.
Obviously I have in my head a very clear picture of how big these are so my gut reaction is just: "Yeah, but these are small, so it's not a problem." I'm just assuming you can see in my head and know the scale, which you can't... at least I hope you can't. (Quick, what number am I thinking of?)
The box shells are 137mm wide by 240mm tall (5.4 by 9.4 inches), so pretty small scale here. Mostly for small pieces and parts.
No I get it completely. My initial response was much different I assure you lol. Then took a step back and heard what you said “it’s not that big”.
You got this.
