In general terms the pricing is done on an individual level based on the material and difficulty of the design. There will as in injection molding be discounts for larger orders of the same design. It is possible for the costumer to buy the rights to the design but is by default the property of Dainaso. The tougher the material is the more expensive the product will be so a part made in PLA will be cheaper than one in ASA or PPS-CF10 etc. The difficulty of the material and properties can be read below.

With this printer I am also able to print parts with different materials if the design is made for it.

If any questions arrive in terms of pricing and material please do not hesitate to contact [here](mailto:dainasosolutions@gmail.com)

### **500W Underwater Scooter – Battery & Charging Upgrade**

This 500W underwater scooter was purchased secondhand in non-working condition. After inspection, it turned out the **original battery was completely dead**.

I decided to replace it with a **custom-built Li-ion battery pack**, tailored to fit the internal space and performance requirements.

During the rebuild, I found the **charging process overly complicated** — it required disassembling the unit, applying grease to the seals, and risking damage to the O-rings each time. To solve this, I integrated a **USB PD-based wireless charging system**, allowing for **safe and convenient recharging** without opening the unit.

A fun challenge in waterproofing, battery design, and wireless power integration — all aimed at making the scooter more user-friendly and reliable.

The Top Ten Lessons We’ve Learned Since Our Initial Launch

Speedboat V2

Speedboat V1

I got inspired by some videos I found on YouTube and decided I wanted to give it a go. The V1 was built on the first printer I partially owned. I borrowed a family friend’s broken printer and was told that if I could get it to work, I could print as much as I wanted. After getting it fixed, I built a jet boat based on a design from [Printables](https://www.printables.com/).

Then, some years later, I decided to pick it up again and design a more powerful version — the V2. It came out pretty great; however, I didn’t run any flow simulations, which later showed it could benefit from added downforce. It turned out so powerful that it would begin to waterplane, and the problem with a waterjet is that it relies on sucking water in and jetting it out — so once it started planing, it struggled to maintain speed.

It’s now disassembled, and I’m planning to upgrade the design with a V3 for next summer.

**Electric Drift Bike – 80 km/h DIY Build**

A friend found an amazing deal on an off-road electric scooter, and we decided to turn it into one of those epic drift bikes you see online. I welded it together using an old childhood bike and the base of a broken high-end chair — all on a tight budget. The result? A wild ride hitting 80 km/h. One of my most fun and fastest builds to date.

Lightdeck

LED Floor demo video

V2 CAD design

After I had created the [Lightdeck](https://dainaso.dk/blog/lightdeck/), I thought the party room could use another upgrade — and this was actually my first attempt at commercializing a product. I looked online and felt that the available options were both too expensive and had too low resolution. From that, I created the V1 model shown below.

The prototype showcased the concept and was actually pretty great. I built it using **open-source Arduino libraries**, which helped accelerate development and made testing animations and patterns much easier. However, since the LEDs were mounted underneath, the floor was raised by around 8 cm — similar to other products, which I felt was too much. That also created a rigidity issue, so I continued developing the design with the goal of making it **cheaper**, **flatter**, and **modular**, since the first version wasn’t.

That led to the V2 design — built from the ground up to be modular, using commercial-grade **CAN bus** communication between tiles, supporting up to 5x5 tiles per controller. Each tile is 90 cm, making a dancefloor of up to 25 m².

Unfortunately, I had to move during the process and didn’t have enough space for the tiles, so I had to postpone the project. But I definitely plan to pick it up again. I’d also like to improve the tile design a bit, since I had to spend over 3 hours manually engraving paths for the LEDs and electronics using a router bit.

Gallery of V2

Gallery of V1

Here is a gallery of both my V1 and V2 E-board that i build within a year. This was before commercial options existed only open scouse forums.


My second homemade e-board is Powered by dual 4.5kW motors, VESCs, and a custom 5S6P Li-Po (now upgraded to 18650 Li-ion). 
The controller was a a modified Wii Nunchuck but due to instability of the signal strength i changed it to a firefly remote it can hit **43 km/h in under 3 seconds** with \~16 km range. The board still works today and is quite fun fun, flexible build that kickstarted my interest in electronics and CAD.


Electric Skateboard

After completing my first custom portable speaker, I learned a lot about sound design, enclosure tuning, and component selection. This second version builds on the same basic design but incorporates every improvement I identified in version one.

The new speaker is significantly larger — increasing internal volume from 3.8 liters to approximately 20 liters. This fivefold increase allows for deeper bass response, more efficient airflow, and overall better acoustic performance.

One of the key upgrades was choosing and sourcing my own speaker drivers. I selected two matching drivers to ensure symmetry and increased output. I browsed several options from driver databases available online — you can view the one I used [here](https://loudspeakerdatabase.com/).

To make an informed decision, I simulated three different drivers in WinISD, evaluating their performance against my design constraints. Based on the results, I chose the driver that offered the best balance between sound quality, efficiency, and enclosure compatibility.

Using the selected driver data, I calculated the optimal box size and port dimensions to match the frequency response goals. This allowed me to design a properly tuned system rather than relying on guesswork.

The enclosure is made from precision-cut wood panels, assembled with interlocking joints. The front panel includes two large drivers positioned symmetrically for stereo sound. In the center is a transparent acrylic window showcasing the internal electronics, including a custom battery pack, controller module, and power distribution. Internal LED lighting adds visibility and aesthetic appeal. The design also incorporates detachable shoulder straps for portability, making it easy to carry.

On the right side of the image, the full CAD model is shown with all major components represented. This includes vent placement, internal volume shaping, and structural supports—all modeled and iterated in Fusion 360 before any physical construction began.

This build is a major leap forward, combining practical experience from the first version with improved simulation, planning, and execution. The result is a far louder, more efficient, and better-looking portable sound system.


Portable Speaker V2

After a frustrating experience at Roskilde Festival in 2018 — where I shared a camp with two poorly built speakers (one that died on day one due to extreme power inefficiency, and another that was so unbalanced it needed a sock stuffed into the tweeter to reduce the output) — I decided to build something better. Something festival-proof. Something legendary.

The result: a **custom-built, high-efficiency speaker system** designed to deliver **60–80 hours of insane sound**, complete with **LED dance lighting** to bring the party to life. My goal was to make a loudspeaker that didn’t just survive RF — it owned it.

This beast connects via **Bluetooth or AUX**, with support for splitting output to **up to five devices**. It's powered by **dual swappable 95Ah batteries**, meaning you can party nonstop without the need to recharge during the entire festival. In fact, it’s consistently finished each Roskilde with **15–35% battery remaining**.

For convenience and security, the system includes **wireless charging**, **dual USB-A ports**, a **locked battery and control box**, and **GPS tracking via AirTags**. It’s been put to the test at Roskilde Festival in **2019, 2022, 2023, 2024**, and **2025**, and it just keeps going.

Along the way, some parts broke — particularly the **membrane shields** — so I designed and 3D printed **stronger replacements in ABS**, chosen for its **UV resistance** and **ductile strength**, making it perfect for outdoor abuse. The original design was built onto a cheap trolley, but after **two trolleys broke**, I ended up welding a **custom steel frame** to support the entire unit — rock-solid and ready for anything.

This project started with a bad speaker experience and turned into one of my most **durable**, **powerful**, and **rewarding builds**.


Festival Loudspeaker

My second homemade e-board, built before commercial options existed. Powered by dual 4.5kW motors, VESCs, and a custom 5S6P Li-Po (now upgraded to 18650 Li-ion). Controlled with a modified Wii Nunchuck, it hit **43 km/h in under 3 seconds** with \~16 km range. Still works today — a fun, flexible build that kickstarted my interest in electronics and CAD.
