I am working on a small hardware prototype for hands-free use with The Handy and similar stroker-style devices, and I am looking for practical feedback from people who understand real-world setups.
The problem I am trying to solve is not device control or software integration. It is the mechanical side: torque, twisting, arm flex, sleeve alignment, and keeping the device stable during VR or seated use.
Current prototype direction:
shorter braced structure instead of a long magic-arm setup
wider clamp/contact areas to reduce twisting
TPU/rubber pads where the mount contacts the body/base/device
elastic strap routing for body/base stabilization
adjustable guide position to help sleeve alignment
compatibility target: The Handy plus a range of sleeve/cup sizes
I would especially like feedback on:
what usually fails first in your hands-free setup: arm flex, clamp slip, sleeve alignment, body movement, or comfort?
whether a body/base stabilized design is more useful than desk-only mounting
whether adjustable guide positioning matters in real use
what dimensions or device/sleeve compatibility issues I should test before making a small pilot batch
I put photos and a short pilot-feedback form here:
This is an early prototype / feedback request, not a broad sales launch. If this is not the right category, please let me know and I can move or remove it.
Ni Hao @fajun_xu or should I say Xu_FaJun?
Well, a while back I did give some thoughts regarding hands-free setups in a previous forum discussion from someone looking for recommendations for a hands-free thrusting fleshlight. I recommend perusing that thread for some insights.
To answer your questions:
What tends to fail most is sleeve alignment IMO vs the other things you mentioned especially in long sessions since one’s GG doesn’t exactly have infinite stamina if you know what I mean and it’s easy to get bored during long sessions causing… slips and misalignments… if you know what I mean… But to be honest tho, that could be a personal matter if you know what I mean…
Body/base IMO is better in regards to keeping things stable, but to be honest I’ve never used desk-mounting before. I think actually this question is a matter of comfort and user preference since not all people engaging with software that uses stroking devices are doing it in the same way given that there’s a rather wide variety of toy types and play configurations that an individual may find comfortable or uncomfortable. I just find base/body mounting more versatile and comfortable vs. being forced to game at desk. Plus, from a market standpoint, there’s a lot of competition for desk mounts since you can simply build that yourself by buying some parts for a stand off Amazon or something and attaching your toy to that. Not many well made toy harnesses tho…
Yes? I guess? Primarily because there are just too many different designs for toys out there and it’s hard to get them all to work with a singular harness type. TBH, I don’t have an issue with this personally since I’ve found my optimal play arrangement and toy preference set-up, but if a product did provide adjustable guides, it would be quite helpful for user comfort and just simple versatility when working with all the different toy types and user preference.
Check out the Awesome List of BPlug supported Onaholes with Linear Actuators for what toys to look into. A short list of toy models to consider looking at: The Fleshy, Joyhub Martino and Mars, Lovense Solace and Solace Pro, of course the Handy, and perhaps the Svakom Hannes Neo. If you’re set on going harness, the two major toy forms you probably need to think about are things like the Fleshy/Hannes Neo/Solace/Joyhub Martino/Mars which are just fleshlight-like devices of various sizes with internal strokers and also toys like the Solace Pro and Handy which have offset external strokers which require a different style of alignment. That of course is for those with GG. No comment on the experience of those on the other side of the coin if you know what I mean, but it would be interesting if such an adjustable harness could work with toys built for the opposite arrangement along with GG… Just a thought…
Anyway, hope my thoughts help you in designing your product! It actually looks pretty interesting! Best of luck!
@blackspherefollower Oy blacksphere! Don’t scare away a newbie who just wanted some feedback on an interesting product they’re designing! Find some light in that black void of a heart you have!
I don’t think refering a new user to the place where their audience really is counts as being scary.
Considering that your AI just spat a whole load of response out that is mostly irrelevant considering the product design, you are on thin ice. Generating essays with no visible experience will not win you points here, and the fact you’re making me do this in a new user’s post really irritates me.
I’m not sure if you’re aware, given the design of your support bracket, but the original handy is going out of production, and the successors all have threaded nut based mounting points, which you might want to consider. You might also want to look at supporting the SSR1 (which given it’s DIY nature, might be a little challenging, but is being used in the VR space due to its low latency).
Thanks, this is exactly the kind of practical feedback I was hoping for.
Your point about sleeve alignment failing first is very useful. I was originally thinking about torque and clamp slip as the main problems, but long-session alignment drift may actually be the better design target to test.
I also agree with your point about body/base mounting. Desk mounts are easier to DIY with Amazon parts, so a body-stabilized or harness-like structure probably has more value if it can stay comfortable and adjustable.
For compatibility, I will separate testing into two groups:
external/offset stroke devices like The Handy and Solace Pro
more inline stroker-style devices like Fleshy, Hannes Neo, Solace, Joyhub Martino/Mars
That helps clarify why the guide position needs to be adjustable rather than fixed. I’ll also look through the previous thread and the supported-device list you linked.
Really appreciate the detailed notes. This gives me a much clearer test checklist before making the next prototype batch.
But to be honest tho, that could be a personal matter if you know what I mean…
