Shampoo Bar Shower Rack

With my recent dive into the sustainability realm I have come upon many new products that require modification of everyday items. One of the main swaps that people make when it comes to hygiene products is switching to a bar version of something that is normally bought in a plastic bottle or tube. This includes shampoo, conditioner, body wash and more; which as you can see, is a lot of bars to store. The conventional shower rack is not built for this many bars which makes it hard to store them conveniently and safely so product isn't wasted. I have designed a shower rack that is meant to hold multiple different bars so they don't slide around and can dry properly. If the bars get wet and sit on a unbreathable surface they begin to breakdown and valuable product gets wasted because of improper storage. The shower rack I have designed has 5 removable slots that can be removed and switched around to meet your needs. Each slot has multiple ventilation slits so the whole bar can dry properly and not slide around. There is also some room on the side for a bottle or two if needed or you can insert another slot. Another feature that makes this different than other racks is that it comes with a removable water shield that can be placed on any side in order to prevent the bars from getting sprayed by the shower. Around the edge there are hooks for holding the shield which also double as holders for razors or anything else that you would usually hang in the shower. This project is almost all done with a 3D printer except a few parts but a way to make it even more sustainable is to use recycled filament or even construct a rack out of containers or scraps you have around your house.

Here is the link for a video I made talking about the process.

1. 3D printer and filament

2. Two waterproof suction cups with hooks

3. Something that can be used as a shield (plastic cover, old plate, etc.)

The rack comes with two different parts that were both modeled in Solidworks and converted to an stl file so they can be printed. The Base rack.stl and Slot.stl files are both available below to be downloaded. The rack has hold for up to 5 slots but you don't need to print/use all 5; so it is up to you how many you want to print. Since I have a small printer I had to split the base rack into two parts and scaled it down to 50% to print so I split the design and included both files below. I added a small latch/hook to help hold the two sides together along with glue.

I have the Tronxy X1 3D printer and that is what I used to print the parts. The base rack is 11.25 inches long so make sure your print bed is large enough before you start printing.

After you have printed the parts its time to assemble! The slots should slide right into the notches in the rack and sit at an angle. The two holes in the bottom are for the suction cup hooks that will hold up the rack. I picked up a pack of two suction cups with hooks at Target for $4 but other types should work as well. If you print in two parts make sure to use waterproof glue and that it is fully dry before you use it.

Unfortunately I was not able to print a full scale model so I do not know all of the issues that may arise with the full size model. I printed it at 50% size and in two pieces and it was very small so that had some issues of its own so please leave feedback if you try printing this.
