I will address many of the questions in this post to help strengthen our mutual understanding.
First, let me introduce CraftyHandy Studio! Born out of passion and built independently from our original company, CraftyHandy Studio combines our interests with professional skills. Through independent operations, we aim to provide more efficient and higher quality services. https://craftyhandy.com/
FMD Printer Selection: We compared various brands of printers and ultimately chose the Bambu Lab P1S and X1 series as our core models. The AMS multi-color filament system allows for fast multi-color printing, and there’s a significant improvement in print quality. We experimented with different printing parameters and various brands of 3D materials, and finally selected stable suppliers and optimal settings.

Quality Control: In addition to ensuring consistent output through optimized parameters and materials, any defective items produced due to unpredictable situations will be directly discarded. This ensures that customers receive high-quality printed parts and can enjoy the experience of assembling their OSR device with a pleasant mood.

Contents of the Material Kit (No soldering required by you): The OSR2+ and SR6 material kits include: 3D-printed parts, all screws, DC connectors, power switch, servos, ESP32, pre-soldered terminal blocks, power adapter, two 30cm straps, DuPont wires and crimp housings, and an assembly wrench. You only need to provide a USB-Type C data cable and a local AC power cord.

Packaging and Shipping: We have upgraded to UPS for shipping. We can deliver to any country UPS serves. Due to Shopify’s limited market reach, customers who cannot place orders through Shopify can pay via PayPal. We will prepare your order, and it will also be protected by PayPal. Delivery Time: You can refer to UPS for accurate arrival times. Typically, UPS offers fast and reliable service, and your order will usually arrive within 3-7 days after shipping.

Additional Shipping Information: We will also be partnering with a freight forwarder to offer another shipping service with better cost efficiency. Stay tuned for more details.

Servo Selection:

Our selected servos: 9imod (brushless and coreless motors) and Standard(DS3225). The reason is that we want to provide users with more options, ensuring a variety of materials to choose from.

What improvements have the author made to the CraftyhandyOSR product?

  1. Heat dissipation is necessary, because up to 6 servos running wildly in a confined space will generate high heat. In order to make the servos have a better working condition and increase their lifespan, heat dissipation is essential.
    A fan slot has been added to the original SR6 base for better heat dissipation.

  2. Customized power bus board, quick and simple installation, and simpler maintenance.

  3. Designed a universal size (100mm*100mm) of the heat dissipation base with independent fans to match SR6 and OSR2+.

  4. Once the fixing hole falls off, it affects the use of the entire device, so we use the hot melt nut method to fix it. Adding hot melt nuts to the SR6 base makes installation easier and faster, and the equipment is more solid and not easy to damage.

  5. Universal adapter, can fix any silicone toy with magic straps

  6. Develop an independent system that can automatically deliver lubricant
    Developed by Craftyhandy, the lubricating fluid is delivered to the Fleshlight via a separate micro
    peristaltic pump delivery system
    Micro peristaltic pump, DC6v-12v planetary reduction 500 motor, high voltage, extrusion pump.

    PWM DC speed control switch
    High-strength PETG 3D printed parts.
    The power supply used should not exceed 5 v

  7. According to many user feedback, the Fleshlight is easy to fall off when using the originally designed Twist4 rotating gear to lock the Fleshlight. Therefore, we fine-tuned the rotating gear to make it lock the Fleshlight more firmly.

Hey, anyone here tried both the old and new versions? What was your vibe with the updates?

Improvement ideas: Considering the possible damage during transportation and the feedback from users on the servo heat dissipation problem, we previously planned to make some changes to the appearance by adding metal parts. So we improved the initial 3D printed bracket model to better metal processing. We produced samples of the improved metal bracket. If anyone has any suggestions, please leave a comment below so that we can work together to make the device better.

Craftyhandy Custom Servos: Premium Performance at a Fraction of the Cost

Competing with established brands like Flash Hobby and 9imod, Craftyhandy’s custom servos deliver ​33% cheaper pricing while matching premium performance.

Why Such a Price Difference?(OSR2 SR6)
Beyond design or feature premiums, the core distinction lies in the servo technology. There are three main types of servos on the market: iron-core, brushless, and Coreless . For example, our standard product uses the ​DS3218 iron-core servo. If noise and longevity aren’t critical concerns, this remains a cost-effective choice.

For enthusiasts demanding higher performance, we’ve developed a ​custom servo that rivals mainstream premium offerings. Our solution mirrors the strategies of leading brands, combining precision engineering and affordability.

Mr. G90ak’s recent servo benchmarking review (see: Servo Roundup Test 1) highlights the superiority of Flash Hobby’s ​M45CHW. Our Craftyhandy servo matches its performance and noise levels while offering a significantly lower price point.

Scaling for Cost Efficiency
With larger order volumes, we can further reduce production costs. We’re open to partnerships with wholesalers, distributors, or retailers eager to slash component expenses and make premium servos accessible to everyone.

At Craftyhandy, we’re committed to minimizing manufacturing costs without compromising quality. Let’s collaborate to bring excellence within reach!
