Bogg Bag Bottle Holder

Bogg bag bottle holder for sunscreen and shampoo bottles.  This works well for multiple bottles using the bag for my daughter's swim lessons.  It also works well for holding a large pump bottle of sunscreen so things don't fall on top of it and pump sunscreen all over the place.  

NOTE: this print worked out great, even despite the crummy looking print showing lots of stringing and blobs.  The organic support tree failed mid-print, so the top two TPU nubs printed really messy and caused a lot of floating strings from the support tree to land in the field of the model.  Since it was such a large print, however, I decided to spend a lot of time cleaning and post processing to make it work.  I haven't printed any other copies because it cleaned up well enough and still and works 100%.  If I had to do it again, I would beef up the support structure.  I had it set to only build the support out of the PETG material, but I think the default Prusa profile for generic PETG leaves the walls too thin to save material.  Perhaps up the support structure perimeters or flow rate so the tree is a bit more substantial.

Printed in PETG for the main body of the holder, and flexible TPU for the four rubber nubs that engage with the Bogg bag holes.

I used a high layer height and speed settings.  Between that and the failed support the quality came out pretty poor.  Those were tradeoffs to have the print complete in less than a day.  You can see the other similar model I made for a Thermacell insect holder that turned out much nicer, using smaller layers.

The solid model I made in Fusion does not have the rubber nubs set as separate pieces.  I did the multi-material setup in the slicer.  I used a combination of cylinder modifiers and paint-on multi-material settings to make the nubs continuous though the side wall of the part.  See the picture of the slicer that shows the cross section of this area to see how it was laid out.  This makes for very solid engagement so you won't have to worry about the nubs breaking free from the rest of the part.  You may be able to do just as well using beam interlocking, but I hadn't experimented with this too much yet, so didn't want to try it on such a large print.

I have made a smaller holder for the Thermacell insect repellant you can see in the first photo.  I'll post that as well some time and will add a link to hit here when I do.

UPDATE SEP 2025: I added another file called Bogg Nub Clip that will attach to the top two nubs from the outside to provide more security and keep them from popping out.  See the latest photos.  This is likely only necessary because my top two nubs didn't print completely because the support structure failed.  But they're available for anyone else if you run into similar problems.  I'd rather print these then redo the entire print.  I made them first out of TPU, those were easy to install, but popped right off when you throw the bag around.  I printed a second copy in PETG.  They were a bit harder to twist on, but so far they're staying in place much better.  Print them in a vertical orientation upside-down to ensure the nub details print accurately (the thicker edge on the print bed, with the rounded corners facing up).
