Most people, the well-wishers we have, have always asked about what we make, and how big it would be ! People also ask how much did it cost, how much will it cost and so on !
We don’t have much answers about the pricing as of now, we expect it to be placed at a maximum of Rs. 1000 / piece.
It is expected to fit into 40 mm x 40 mm x 30 mm cuboid without the cables, which will be permanently attached to the device.
The device would come only in black matte finish colour.
The complete case would be 3D printed for the initial lot or until the next version.
Initial 100 pieces of the production will be sold at a discounted rate, and upon the feedback received, updated and put into production at the normal pricing. The initial pieces is expected come with extended replacement warranty compared to the standard warranty provided and in case of major issues, replaced completely.
The finalized update regarding these will only be available by March 2019. The indicative image of the product is given below
Stay tuned for the updates ! And thank you for the support 🙂
We have our RDOne Electronics hardware prototyping almost in its final stage. We had earlier gone for white case colour in our 3D Print designs. We have changed that to Black and will mostly be matte finish.
We have, in this updated case design, accommodated indication on skin display indication. We have also rectified the design changes, and improved the placement with legs for the case. This design will be almost ready for production, and we hope it will be 🙂
Stay tuned for more updates. We will, hopefully, be getting back with the prototype in a week or two !
A few days back, we had given a brief introduction on 3D printing that we had done for prototyping stage. Once the 3D Printing was done, and tested, we understood that there are a few difference between 3D Printed plastics when compared to the molded ones. For instance, we had a screwing mechanism to be used to screw in the PCB and cover to the main body. We were planning for a M2 x 6 mm screw to be used and thought of going with 1.9 mm hole so that the screw can create it’s own thread while being screwed.
Little did we know that while using 3D printing, there are chances that the material might flow in and out a bit, changing the dimensions. This means that our 1.9 mm hole in drawing will in actual model would be somewhere much less than 1.9 mm. Our 3D printing friend, Magesh, gave us a suggestion of going with +0.1 mm for the dimension of hole.
If the screw hole is more, you can always use ABS glue to reduce the size of the hole. ABS glue, as I read, is made by mixing ABS Plastic in acetone. We will try this method, and keep you updated !

When building an electronic product that is to be directly marketed to the customer, it mostly has to come with a case or a cover. When it comes to building that, the cost becomes a major concern, especially for a start up. The big companies often has cash in their hand to start producing at bigger scales, which lowers the cost per piece as well as gives them better profit margins.
As a startup firm, with very small amount of cash in hand, we were not able to invest a lot in molding methods, as we were not sure about the customer reception of our product. We obviously wanted to eliminate risks involved or bring it down to a very low level.
We tried the new technology of 3D Printing. To begin with, we had no idea on how good it would be. The above image is our version 2 of 3D Prints with ABS Plastic. We chose ABS over PLA due to its thermal stability at higher temperatures.
Why did we choose to use 3D Printing ?
We chose 3D printing due to its lower initial investment. We compared the price point of cost per piece of 3D printed and molded plastic cases. We found that, for a startup which expects to slowly ramp up the production, and is quite unsure of the production volume, a 3D Printed case would be good.
Where did we get it printed ?
We browsed through a lot of online options and then chose Magesh for our 3D prototype printing and for the 3D printing related technical helps.
What material did we choose ?
We chose ABS Plastic because of its better thermal properties compared to PLA. The other material options were much costly compared to these, and were not viable to be used.
What next ?
We would upgrade the structure, and correct errors when gearing to our next version, which will be a near-to-production model.
