Segufix alternative?

Post by ZipMeUp »

I have always wanted to be in Segufix bondage because it's adjustable, inescapable, and comfortable while being snug and (as described by other members) positively "yummy".

I just ordered a bunch of 3/4" cam buckles and webbing for organizing tarps, etc. and had an idea: I think I might be able to make something quite similar to Segufix. The system would consist of plastic clamshells with internal tabs that would allow the buckles to retract into them and lock. Similar to the article I posted about turning cam buckles into zip ties with metal clamshell thingies.

Since they could be 3d printed (I have a MakerBot and it produces quite strong prints from PETG), I will make a series of clamshells with internal locking tabs that will allow the buckles, once fastened, to slide into them. I will then build a harness from the webbing (it's pretty cheap, like 50 cents a foot). Shoulder harness, Crotch harness, and body harness with two straps running vertically down my back / chest. After putting the harness on and sliding the clamshells over the buckles, it will be impossible to release without a (3d printed) key that depresses all the tabs in the PETG clamshell simultaneously.

Actually this is in a way better than Seggufix. Once I am bound, I can always cinch the bondage tighter. Being able to adjust... erm... :gag: >> tighten << :gag: the bondage after application has always been a must for me.

Finally, the safety part. I will hook this to two anchors in the floor with a door lock electromagnet connected to a timer with enough battery charge to last a bit longer than the timer is set for. Even if my timer code crashes (it never has), the battery will run out and I will be free whether Mr. Murphy wants me to or not.

The straps arrived yesterday and I'm glad I ordered 5 feet more strap than initially intended... I only have 3 feet left.
I ended up making a Segufix-style body harness as described earlier. Although I don't post IRL pictures, it is set up as follows:
  • [1] Strap running from small of back, down, between legs, terminating at waist with 2 buckles
  • [2] Strap attached to [1] at shoulder blade level, running under arms
  • [3] Strap attached to [1] at waist level, as a "belt"
  • [4] Two straps, one over each shoulder, attached to [1] behind neck and running to the buckles on [1]
  • [5] Buckle to hold the straps of [4] together at chest level, fairly short but necessary to prevent [4] from slipping off shoulders

The buckle:
  • [1] 3/4 inch heavy duty polyester webbing from strapworks.com
  • [2] 3/4 inch metal cam buckle, also from strapworks.com
  • [3] 3D printed Locking tab that goes into the bottom of [2] and keeps [2] stuck in [4]
  • [4] 3D printed Clamshell that goes over [2] and [3]
  • [5] Holes in the top and bottom of [4] that allow a small screwdriver to release the belt or the mechanism

With the bondage harness complete, it's time to compare it the the Segufixxx bondage that everyone loves. For $50 in materials and 8 hours in labor, it's not a bad alternative, especially if you like your bondage super tight.

SEGUFIX:
Security: :gag: :gag: :gag: :gag: :gag: From other member's posts, Segufix is impossible to open without a strong magnet and could probably restrain a horse.
Comfort: :gag: :gag: :gag: :gag: :gag: Segufix is very comfortable and is designed for institutional use.
Ease of use: :gag: :gag: :gag: :gag: The system is relatively easy to apply.
Cost: :gag: Segufix is one of the most expensive bondage kits out there.
Concealability: :gag: :gag: The straps are somewhat bulky but not as hard to hide as a bench or similar.
Zzzzip factor: :gag: It cannot be tightened after application.

SEGUFIX-ALTERNATIVE:
Security: :gag: :gag: :gag: :gag: A lot of things can get into the clamshell and loosen the buckle, If you can avoid that it's probably inescapable.
Comfort: :gag: :gag: :gag: :gag: The straps are a bit narrower than Segufix, but the thickness prevents them from bunching up like rope.
Ease of use: :gag: :gag: :gag: :gag: :gag: With the locking tab attached to the buckle with thread and glue, application is a cinch (no pun intended :lol: )
Cost: :gag: :gag: :gag: :gag: :gag: If you can sew webbing and have a 3d printer, this is 10x cheaper than Segufix. Even if you have to buy a printer and supplies, it still costs a bit less.
Concealability: :gag: :gag: :gag: :gag: The straps and buckles fold into a 3x3x3 inch ball. Fairly easy to conceal.
Zzzip factor: :gag: :gag: :gag: :gag: Although there is some resistance to tightening, it is easy enough to tighten them. If I am not careful I can make them :gag: too tight :gag:

Next task is to build a frame to secure the harness too. I'll use some heavy PVC and elbows for that. Given that I tend to build things using PVC already this should be very easy to conceal. $40 more should make me a very sturdy and inescapable frame.
It it ain't inescapable... It ain't my kind of bondage.

Would LOVE to get more details on this. I'm looking for a segufix alternative. I am about to buy a 3D printer and looking at rivet punchers. Any chance you would be willing to share your design? I don't get the picture above.

As for segufix, there are alternative suppliers that are slightly cheaper, and you can buy just the locks separately at roughly €10 each. The straps can be made yourself from cotton or polyester webbing, eyelets and velcro. I've been contemplating lots of designs myself but keep failing to find the time to actually make anything. For a cheap alternative a you can use a straight clevis pin (like this for example) with a small padlock through it. I found I usually need to drill the crosshole a little larger and I add a washer above and below the strap to help spread the load. An M8 pin fits quite snug in the hole, M6 works too but really needs the washers and there is a lot less metal left around the cross hole if you have to drill it out.

Alternative for the locks is 3d printing some yourself. Apparently this design works quite well, though it uses a plastic locking post so is probably less strong than a metal on. If properly applied it should be all but impossible to load a locking system like this to the point it would be possible to break one though :twisted:

The SAE 1/4 inch size washers it uses are however near unobtainium where I live ao I've got a couple of boxes of different metric washers and the requisite magnets waiting for me to find the time to do some experimenting to make a working version using metric washers. Likely it'll be a thick M6 washer drilled out to 7.5mm with a slight redesign of the locking post and lower cap to make it work.

For your first experiments you don't need any specialised tools apart from a hammer. Most eyelet and rivet kits come with a hammer tool. While not ideal if you want to do many of them, for just a few as an experiment it's just fine.

Aloha from Bound Anna, Goats.
Bondage is like a foreign film without subtitles. Only through sharing and practice can we hope to understand.

Thank you all for the welcome and the suggestions. I honestly did not expect a reply :).

I love the idea of a cam buckle "shell" that has a hole to insert a screwdriver in to release. That's my next project.

Thanks all!

I don't get on BoundAnna that often but I'd be glad to provide the files.
It's designed with FreeCad.
Since the forum won't allow .fcstd or .stl files, you'll have to rename them before using them.
I've also attached STL's of the parts.
