Modular Spice Rack (45mmx45mm Square Bottles)

After taking the step of buying matching white label spice bottles I was faced with making a decision as to how I'd store them. Storing them in the box they came in helped kick the can down the road long enough for me to become incredibly indecisive about the matter, so I came up with a solution that works in more than one way, and finally got around to printing something. 

These three bottle modules work as standalones, horizontal stacking units, or vertical nesting units. Standalones work well for grouping three spices that are commonly used together, the horizontal stacks work well in a width that is a multiple of ~21cm/~8" (there's about a half inch/1.5mm wiggle room per unit width built into the design), and the vertical nesting is ideal for counters or drawers with at least 12cm/4.5" clearance. 

There's no need for supports or any special printing or material considerations, they should print fine with up to a 0.8mm nozzle, and the taller the layer height, the better. I managed to fit up to three at a time on a MK3 bed, and one should fit diagonally on a mini bed. I printed the final set in PETG, but TPU and PLA will work just as well. If you can't get a tight friction fit between several units, gluing them together or bracing the group will help with stability. I considered adding an option to snap or bolt them together, but stopped short to finally get them printed out after an embarrassingly long stint of indecisiveness. 

If you have any questions or modification requests, let me know, and if you print some, please upload a make. 

Edit 8/12/2023: added an add on (corner tilt) and full model (corner tilt full) that lets the model rest in a more stable vertical orientation per the request of @CumpsD_121140
