QUALITY MODIFIED CUSTOM OSR2+ & SR6 BUILDS
Looking for next-level realism in male toy robotics?
This fully customised, feature-packed unit has been upgraded for durability, performance, aesthetics and ease of use — a big step forward from the original.
Finally experience multi-axis — .roll, .pitch and .twist — where you switch it on and expect a high-quality device with ZERO complications.
Why choose the VESPERA release?
High-quality, low-inertia coreless HV servos, quality-checked and selected for quietness — motors that last years of daily use without failure. Firmware optimised for smoothness and refresh rate.
Heatsink design — a silent cooling alternative proven just as effective as a fan… also aesthetics.
Future-proofed PCB — 4 additional 3-pin connectors, a 4-pin OLED/fan connector and a JST fan connector. A custom 2oz copper PCB from JLCPCB designed with the OSR2+/SR6 in mind.
Premium components — all premium-grade, no compromises, for reliable long-term performance.
Meticulous craftsmanship — every unit expertly assembled and precisely fine-tuned for a fuss-free experience.
Modified STLs — every model altered for geometric strength, functionality and looks.
Developed with experience — 220+ units dispatched. SR tinkering since 2021, OSR2s offered since 2023, SR6 since 2024.
Key features & enhancements
- ESP32 CP210 chipset — wired or WiFi. WiFi built into the system, easy connection via a phone or PC. Open source, mod as you wish.
- vESP power delivery PCB — goodbye stripped wires and WAGOs. Plug-and-play maintenance.
- Heatsink design — silent, using 40 mm aluminium heatsinks.
- Reinforced power connection — 5.5 × 2.5 mm plated jack with a silicone protective cover.
- Full metal motors — 45 kg coreless servos for smooth, powerful, quiet operation. These are the servos and torque ratings I settled on after testing many brands and variants. Low inertia — no harsh desk vibrations, with unparalleled acceleration.
- Vibration dampening — rubber dampeners, EVA foam and metal-rubber M4 mounts included.
- Easy case clip — open/release tab for hassle-free case and adapter changes.
- Metal carbon-rod pitch arm — M4 metal arms for looks, durability and lower weight. Simply better than plastic.
- Organised cable management — cables sleeved, internals secured.
- High print quality — every part printed on Bambu Lab P1S / A1 / P2S printers.
- Modified STL files — revisited and remodelled over the years with durability in mind.
- 270° coreless twist module pre-installed — many users swear by twist and so do I. It is something you will want.
- FREE stable desk mount — dual-screw mount included for a rock-solid setup.
- SR6 upgrades — thicker internal chassis with M4 screws instead of M3 to solidify the motor gantry. OLED display and 4010 blower fan pre-installed on every SR6.
Customisation options
I have worked in 3D design and manufacturing for over a decade. Choose any colour in any combination, alongside any pattern, with a logo. If the logo isn’t pre-vectorised I’ll do that for you at no extra cost. Not fussed about a theme? I keep pre-determined colourways in stock for faster delivery. If you wonder why bother when it isn’t cost- or time-effective: I do this because I enjoy it, and delivering quality is something I don’t overlook.
Custom units have over 19 accent patterns to choose from, and I can model your logo from whatever image or inspiration you like. Even if the idea is vague I’ll help you land on something you really enjoy — e.g. AI prompt generation.

Some Newer Builds:
Included with every order
- Dual-screw VESA desk mount — secure, stable mounting, tried and tested.
- Spare parts kit — alternative-coloured front plates / pitch lid in textured PET, plus an extra set of bearing arms, free — for convenience and peace of mind.
- Vibration-dampening accessories — M4 metal-rubber mounts, EVA foam and rubber dampeners for smooth, quiet operation.
- Twist transfer gear — a spare, as it can be a point of wear over time. The updated receiver makes swaps easy.
- Extra throwaways — spares throughout production that did not make the cut, included because why not.
- 2oz Custom vESP PCB — PCB designed with numerous ceramic capacitors and electrolytic bulk cap for clean and stable electrical distribution.
I try my best to bring value at this price point, and every customer is appreciated.
How is the build quality? Will it last?
You guys have shown me so much love since 2023, so I’ve worked hard to improve in every way. I started on EroScripts with simple Ender 3s and have since moved to a full array of Bambu Lab printers: refined variable layer heights of 0.18 / 0.2 mm and a significantly higher infill ratio, even on aesthetic parts. Their dimensional accuracy let me revisit and optimise every model and STL, reinforcing the geometric weak points for strength and looks. What I send out is something I’m genuinely proud to have made. Free spare arms and spares are in every package — just in case you spin your chair and…

Pricing & payment
OSR2 — upgraded units start at £215 + shipping.
SR6 — modified units start at £355 + shipping.
Case adapters £5 each — Go, Flight, Quickshot.
Caseless adapters £7.50 each — Khrulls Mod, VAMRobots, Large Caseless, Kiiroo ‘Feelstars’ (all updated to be of better structural support)
Prices are driven primarily by the bill of materials; there is a modest maker’s fee, kept as low as I can especially with all the parts that do not meet your eyes and should never.
All caseless adapters are printed in PETG for the best resistance to cantilevered stress — maximum durability and strength.
FAQ
Q: How do I place an order?
A: On the website at buyosr2sr6.com/order, or by DM — I’ll guide you through payment and customisation and keep you updated daily.
Q: Which payment methods do you take?
A: On the site: card, Apple Pay, Google Pay, Shop Pay and Klarna. By DM: PayPal (F&F) and Wise transfer — Wise has the best international currency conversion fees.
Q: Do you sell the SR6?
A: Yes. DM me if you’d like to know in much more detail what I’ve done with it so far.
Q: Can I get adapters for products like the Kiiroo Keon, or niche onaholes?
A: Yes. Adapters for most popular toys are available — send a DM with what you need. Many have been modified for better fit and usability.
Q: Besides the OSR2+, do I need anything else?
A: Yes — a power supply, a USB-C cable, and a PC or phone to connect the WIFI if you prefer over USB. DM me for the full list of optional accessories.
Q: Do you sell the T-Valve?
A: No. It’s unnecessary — wire clutter and extra noise for no noticeable benefit. I can include the cables for one if you want it anyway.
Q: What is your print quality like?
A: 0.18–0.2 mm variable layer heights, 30–60 % infill and 3–4 walls depending on the part, at 0.2 resolution. All prints at 30 mm/s with gyroid or cubic infill chosen for structural need. With nearly a decade of 3D printing experience, every unit looks clean and performs reliably.
