Prototype 13


Prototype 13

So, taking into account the conclusions from last prototype, we started creating a mold for the silicone. We laser cut plexy glass with the same shape and size of the 3D print pattern. And we poured the silicone there.



About the 3D print, we changed it, deleting the part of the connection and creating a space to assembly the metal part. We made some holes there and we assembly it.



The silicone was difficult to get out of the mold and we had to cut the borders of the hexagones to be able to assembly it.


After puting the velcro straps we went to test it with Sander and the biggest problem was that the connection was too small so it could not fit in his bike; so we decided to take off the rubber part to be able to test it.

The strength is okay
The silicone part must be changed
the support must be more in the front (change the CAD model).
To big connection to the bike

After prototype 11 we reached some conclusions as it can be seen in the previous post, so we decided to change a little bit the 3D printed part. We made the thickness double, 4 mm concretely. Also, we made the cylinder stronger, so we made it thicker too and added some material and edge blends.



Even if the product was stronger this way, we saw that is not enough. We need a stronger connection to the bike, and the PLA is not a good option.

Lot of support
Still weal connection to the bike
Easy to slide of the handlebar
Still not enough room for silicone
Adjustable to every hand
To big connection to the bike



So, for the next prototype, the most important aspect to have into account is that we must make a stronger connection to avoid break. Also, we decided to pour the silicone all over the 3D print, and not just in the middle part. Another conclusion was, that the holes for the straps must be bigger, and they must have more material around to make it stronger.
