Introduction & Acknowledgments

Before we get into the details, I want to thank @g90ak. If you’ve spent any time on Eroscripts, you’ve likely seen his amazing work. His OSR2+ drops inspired me heavily in starting my own project. You can check out his main post here:

My project builds on the SSR1 design by @Tempest, who also created the SR6, OSR2, and other innovative devices. If you aren’t familiar with his work, I recommend visiting his Patreon:

Firmware included is created by @Khrull … Creator of the awesome XTPlayer. https://www.patreon.com/c/Khrull/


What Is the SSR1?

The SSR1 (Silent Stroker Robot) is a single-axis, belt-driven stroker device powered by a brushless motor and controlled via T-Code. Known for its smooth, quiet operation and excellent performance, it’s a go-to for users wanting quiet, reliable, single-axis action.


What Is the SSR M1?

The SSR M1 (Modular) is my take on the SSR1 Beta—redesigned for modularity, user serviceability, and customization.



Key Modular Features

Picatinny Rail Mounting System

Finding the perfect mounting position with an OSR2 or SSR1 can be tricky. My solution: a standard Picatinny rail for secure mounting with fine adjustment.

  • Works with a variety of attachments, including handles.
  • Adds a customizable visual element with color accents.
  • Includes a Picatinny-to-VESA adapter compatible with 100×100 mm VESA mounts (works with monitor arms and desk mounts).


Quick-Release Receiver

A modified quick-release bracket receiver makes storage and receiver changes fast and simple.

  • Ships standard with a Fleshlight-compatible receiver (black case recommended).
  • Optional receivers for Handy sleeves and Kiiroo strokers available.

Power Switch Addition

I’ve added a dedicated on/off switch—a must-have for safety and convenience, especially when a script suddenly ramps up speed post-finish.

Neat, always good to see community members selling their own designs. I’m not currently looking for another device at the moment since I’ve got the Keon as a daily driver and an OSR2 for more intense sessions, but I have a few notes/questions.

Are the usb c ports marked for which one is for power and which one is for the data?

What’s the material and how durable is it?

I assume battery plate is referring to the powertool batteries and I would assume you’d have a diff plate for each brand since iirc they aren’t compatible with one another.

What do you mean by Molded plastic case with foam insert? Is this like the ergo case design that Tempest has(this would be something I’d be interested in to replace the Keon(the ergo/keon case gives me something to press against so I’m at the bottom of the stroke and don’t have to worry about moving forward by accident)) or is this something else?

First of all these are all great questions!

Marking of ports:
They are not currently marked. This is something that I was wondering if I should do. This is probably something that I will do on the next batch. Currently the easiest way to tell is that I placed the power button on the same side as the power port.

Material/Durability: I’m actually in the middle of testing a few different options for filament type. My first batch consists of 2 made out of PLA and 2 made from PETG. I’m most likely going to Start making everything out of PETG in my next batch to provide a little bit better durability. With how good the original design is combined the testing that I’m doing, I’m not seeing any durability issues.
This is one advantage of small batches though. It will allow me to identify particular issues easily and allows the user to reach out directly if something comes up.

The battery plate: Yes, I intend on making a plate for each major 20V battery on the market. Dewalt, Milwaukee, Ryobi, Makita, Black and Decker. My main issue currently is having to procure the other batteries for testing purposes.

The case: My apologies… I definitely see how my wording could have caused confusion. What I meant was a storage case like this


I’m currently trying to balance value, quality and making sure that it has enough space to store the device, a power supply, the picatinny to vesa adapter and a few receivers.

Let me know if you have any more questions.

My next batch will probably be marked like this.
