3D printers filament is sold in weight; the most common packages are 1 or 2 Kg filament rolls. The reason is that the product format, i.e. the filament in our case is the most important aspect for the end-user but meaningless for producers. Producers just sell kilograms of plastic material (PLA or ABS); the filament is the form factor provided on the market for a specific usage.
For a similar reason 3D printers users needs to measure their filament in length. Slicer algorithms calculate the meter of filament needed for a certain 3D printed object so it is important to know how much meters remain in the roll before starting a new object printing and how many meters are used during a print job.
Based on the specific weight of the materials used for 3D printing (PLA and ABS have different specific weight) and the filament diameter we are able to dynamically calculate the consumption and remained filament on the spool in grams or kilograms as well as centineters or meters.
This kit solves a great issue I have experienced working a lot with 3D printers: controlling the filament consumption while the 3D printer is working. After exploring several possible approaches I decided that the most reliable solution should be based on the weight control.
And the ability to dynamically measure the plastic material (filament) in use by a 3D printer includes some interesting non-obvious aspects helpful in many phases of the 3D printing process.

We recognize our top users by making them a Tindarian. Tindarians have access to secret & unreleased features.
We look for the most active & best members of the Tindie community, and invite them to join. There isn't a selection process or form to fill out. The only way to become a Tindarian is by being a nice & active member of the Tindie community!
I developed software and firmware for embedded devices, Android, Mac and Linux. I frequently rethink projects or create new ones in order to make products and prototypes market-affordable and as cheap as possible without compromising quality.
Who is Balearic Dynamics ...
FROM PRINTERS TO CIRCUITS
About five years ago I created the IbizaSocialPrinters brand, supporting the marketing for the hardware and software development of the first Bluetooth POS printer driver for Android. Then, things grew up and I was involved in wider and more complex projects.
Most of these projects needed software and hardware development. To make things faster the better way was to be able to manage the entire prototyping process in-home, reducing the waiting time almost to zero. When I started making the circuits and small mechanical parts together with circuit design, PCB layout, microcontroller firmware, and application software the new brand "Balearic Dynamics" came to life.
THE NEW BRAND
If you loved the "Fringe" series, you will sure remember the "Massive Dynamics" big company, that inspired the idea for the logo. The name for the new brand was still in doubt. Around the middle of December 2013, the news spread that "Google acquired the robotics company Boston Dynamics" So, why not creating the Balearic Dynamics as well?
THE SIMPLIFICATION PROCESS
I frequently see that many makers, creators, inventors, hobbyists and so on approach electronic engineering in a very simple and less efficient way. What the market offers is a great number of DIY projects that in fact have very few chances to be used in the real world. In brief, the approach is bottom-top.
When things become more complex they fail, just because omitting apparently useless components makes things simple but not in the correct sense.
On the contrary, developing some complex architecture, some circuits parts can be shared among many projects. That is, our Arduino compatible kits: tools we already use as part of our projects now transformed in independent open-hardware modules for the customers.
This is also why - following the Open Source and Creative Commons philosophy - these projects are sold at a very reasonable price, full documented and explained.
I appreciate very much the opportunity to publish the entire project of every product on the popular on-line magazine electroschematics.com and, of course, on the main site www.balearidcynamics.com
