[Stokke Bathtub] Design and 3D print a replacement piece to fold the Stokke Flexi Bath

Short new project that i needed to tacle due to space constraint we have. We own a Stokke bathtub for baby that can fold and has originally an attach to keep it folded that is part of the tub.
Unfortunately, the attach fell off and without it the tub stay unfolded and take much more space.

The idea was to take the already existing design for the attaching side and incorporate it in a 2 headed hook that would manage to keep the tub folded.

For that i took a few shots of the broken part and imported those in Adobe Illustrator in order to trace a profile of the part. With this profile path line, i could generate a .svg file that can be imported as a sketch in 123D Design

The broken part from top and profile :


Then i  designed the profile and i came up with that seemed to be the closed to the real hook. I generated a .svg file out of illustrator which can be read by the CAD software :

After importing the .svg file in 123D Design, i could extrude the volume out of the profile. For additional fun i also decided the incorporate the real logo of Stokke in the design :

After having generating the .stl file from the CAD software i handed it to my electronic shop that own a 3d printer (http://www.wigi.fr/) and they nicely printed it in a nice shiny black.

The final result is quite nice for a small piece. There are slight issues arround the edges of both hooks, but that is normal since this was printed without any support material. 

And then how it looks when used with the actual bath tub !

Contact me directly if you have any question, do not hesitate to ask. I will put the design on thingiverse when i have time. 

EDIT : The thingiverse link with access to the .stl file for your own convenience !

[Wireless Room Temperature Monitoring System] 3D Printed enclosure final result !

After so many weeks of inactivy (I have very good reasons i promise) i finally had the time to finish the CAD file for the enclosure and to get it printed at my local store in Alsace :)

Here is the final result. It is far from perfect unfortunately. I didnt plan for the support to get merged with some of the structure i designed. Also some of the structure were too small and had small hanging part, under which support material was still put and unfortunately ... i had to cut the whole thing to make it work. Here are a few thing that i would do differently next time :

On the left, i was too optimistic to have the small bump to guide the arduino mini pro ... unfortunately since there was hanging part over it, the bumps got merged with the support material ... i ended up remove the whole top part. Same issue with the one in the middle ... the support material added by the 3D printing software screwed the print. On the right, i made a different mistake to put the screwing hole for the temperature sensor above a another guide... i didnt plan for the support material for the screwing hole to merge with the structure below ...

Here are the pictures of the final result ! Let me know your thoughts or suggestions !

[Wireless Room Temperature Monitoring System] Enclosure for wireless temperature sensor 3D Modeling with 123D Design

Now that the components are all designed in 3D i can try an design the enclosure.

I tried to take into account the way the elements are going together, how the cables are connecting the components and all. I am not even sure this could be 3D printed. Here is what i intend to send for printing :

What do you think ? Any suggestions ?

[Wireless Room Temperature Monitoring System] Enclosure for wireless temperature sensor 3D Modeling with 123D Design

Alright so now that i have a rough idea of how the enclosure should be i can go ahead and design it in CAD. 123D Design seems perfect and easy to use. As a training exercice I decided to reproduce all the components that are involved in my sensor in 123D Design at the exact correct scale. This way i will be able to design the enclosure to take into account. First i took exact measurement of each of the 5 main components that are involved in the sensor.

Here is how it looks :

Here is a picture of the real stuff :)

What do you think ?  Any advice ?

If anyone is interested for their own CAD design (and if you use the same components as me ...) please contact me and i will give you the .stl file

Next, i will make the enclosure using those components to make sure that everything fits together

[Wireless Room Temperature Monitoring System] Sensor Enclosure Prototyping Part 1

I have been doing some thinking on the enclosure i want to 3D Print myself.

The goal is to have a relatively simple design to store all modules : Arduino, Temperature sensor, 9V Battery enclosure and TX RF 433 Mhz Module.

Here are the first prototype drawings :

 

I am already having second thoughts about the enclosure, specifically about the antenna. My latest test showed that i should have a linear antenna instead of a coiled one...

I will have some more drawing done in the following days.
