Gối đỡ chai rượu cho kệ IKEA Kallax

I have the IKEA Kallax wine shelf insert in my shelf unit, and use it to hold some wine bottles. However, the unit doesn't support the bottles at all, and there is some space inside, which leads to the bottles rolling back and forth slightly and making annoying noise. So, I printed these simple cradles that fit inside and hold the bottles nicely in place. The cradles can be placed in unsecured, or can be glued in place (this is what I did), and the shape allows bottles to freely slide in and out just as easily as before.

To make this, print two of the provided STL for each bottle space you want an insert for. You'll need to glue these two pieces together (the STL comes with alignment tabs that make assembling easy), but that's all there is to it!

Print in whatever material you want, with minimal infill (I did 10%, 5% may work fine but I haven't tested it). I also printed in different colors to match the material the cradle was inserted on.
