This is one of my favorite models of more than a hundred downloads of other models. I have the ability to design similar models but every model I make usually takes on multiple starts-stops-start over moments with lots of test printing. There was never a print that did not fit as intended. I do have times with printing the double XL box, it will fail with spaghetti but that is about one out of 5 or 6. And, it is likely something I am doing wrong.

I cannot get enough of this guys stuff. Very well designed.

The threads are a dream: smooth as can be.

The design prints very well but the actual use with a bottle of the water reveals issues. The angle of the holder is perfect but trying to disconnect the bottle can be a bit tedious. I rated it as a 5, because the print worked perfect and the clip mates perfect to the bottle. It just needs a bit more work to make it exception. My experience may not be common so I did not want my rating to detract from others trying it. And it does not use much filament so "no harm, no foul."

I have meant to write sooner but I have gotten more value out of these files than any other single design. My favorite is the XL double box with all of the different configurations of the inserts. I have modified some of the inserts to accommodate some unique situations.
