Happy Brush Elmex Aronal Toothbrush Stand

Motivation

Having different tooth brushes (Happy Brush and a standard one) and also different toothpaste tubes (Elmex/Aronal and a different brand in case of my wife) standing on our bathroom shelf demanded for a better organization. I found a lot of stand that looked nice, but never matched our setup 100%. Unfortunately I couldn't find model sources for better remixing as compared to slicing and patching numerous STL files. So I modeled a base shape that addressed my needs - and hopefully yours as well.

Summary

If you find the attached STLs useful for you. Just print. End of story. 

But wait. What if you like the basic body but have some extra wishes? Read on - and hopefully you also get an easy way forward to remix yours. You will need Fusion360 for that or any other 3D design workbench that can import those f3d files. 

This toothbrush stand is made for flexible mixing and matching of model parts that make up the complete stand. The parts are for mixing differently sized holes for different brands of electric and manual toothbrushes and/or toothpastes. Feel free to remix.

Please note that the complete stand as showed above is not meant to be printed as such. It might be a bit oversized ;-). Instead, a combination of individual segments is printed.

The combinations that I thought of being the most interesting ones are supplied as STLs for direct printing. 

Printing

The print direction, when you look at the images, is from front to back, so that the loop of the print body resides on your print bed. 

No supports are needed.

I successfully printed with 0.2mm layer height using PLA.

The seam positioning may be of interest for getting a nice surface. Best is to position it at the bottom of the stand.

Remixing

Depending on what exactly you want to do, I recommend different approaches. Easiest first, more difficult one last.

If you are fine with a combination of the prebuilt segments, you can go with hiding and moving body segments.

If you need other hole diameters or want to go for any other segment structure, then you can go for the second approach (extending the upper and lower bar).

If you want a different base shape, because the model is too deep for putting it where you want it in your bathroom, you still can remix it with the third approach. But this needs to extrude a quarter of the model to the new shape.

Approaches

Hide and move body segments

The easiest way to get another combination or number of already defined holes is to use Fusion360 and just hide the unwanted parts of the overall body. Then you just have to move the parts for a (un-)connected body. You don't have to merge the parts for printing them! Export the nicely arranged visible parts, then export as STL and you are ready to print. 

Finally, redo the moves and the hiding or just don't save the Fusion360 project. 

Extend upper and lower bars and drill new holes on a new segment

Same as above, plus create a new segment by first moving one of the rounded ends of the model, then extend/extrude the upper and lower bars to the needed length for your new holes.

Create the extrusion as new bodies for later recombination. Then drill your holes as you need them on your new segment. Reposition the model end. Hide and move the model segments as needed, then export as STL.

Start with solid quarter of the model w/o holes

This is needed when you want the model to have a different depth. The current model is designed for holes with max hole diameter of about 45mm. The inner surface is 50mm.

First, you expand the U-shape to the back until reaching half of the overall depth. Then you mirror the whole part at its backside, doubling its depth. After that, you are ready to expand the upper and lower bars to the right until reaching the planned mid of the model. 

Now you mirror the U-shape at the face through your right end of the model, yielding the resulting base model w/o holes. Then drill your holes as needed. 

Remixed and related Projects

I didn'd remix directly from a project. However I liked the overall shape of the stand in "Designer Toothbrush Holder w/ Flow Control by LaunchLab" on Thingiverse which inspired me to build a similar shape in Fusion360.
