Motorize nipple puller

Post by occorics »

I have finished my newest project today, a motorized nipple-puller with a chest-strap
The stepper-motor might be a bit overkill, but i had that one in the drawer.
I have tested with 5kg of weight and it could easily lift that and from the test with the clover-clamps, i had the impression, that they could easily be pulled off...
The arm can move by 18cm, again more than needed, but i'm thinking about using it to pull off clothespins on strings with different lengths...

It's connected to my remote-control box, so it can be operated from afar...

:shock:

The combination of a stepper motor and a threaded rod is crazy strong.

People use that as the Z-axis on 3D-printers, and if something blocks it, things are torn apart/squashed (depending on the direction).

You could end up with some really long nipples!

these are actually 3D-printer parts...
i can adjust the length of my nipples in steps of 0.04mm :rofl:

as i said, the current stepper is overkill. i'll probably replace it with a smaller one or at least limit the current...

As far as I can make out, the idea that clover clamps don't let go is a myth. If the stepper motor doesn't stop, they'll pull off. It'll hurt, but I thought that was kinda the point. :twisted:

I'm very curious. How is this powered and how do you control it?

There's a Raspberry Pi in it that controls a stepper-motor driver (and other toys). It runs a web-server, so everything can be controlled remotely.

Seems i was using the wrong wording. I'm merely interested how the nippel puller strap is connected to your control box (cable, wireless, infrared or ultrasonic) and how it is powered (if remote controlled).

ah, ok...
there's a RJ45 connector on the side of the motor (facing the box in the pic). I use a standard cat5 cable to connect it.

Lady Helena proved last night, that the motor is strong enough to pull off clover-clamps with ease...
Before we started, She announced, that the next 30 minutes would be more fun for Her than for me and i knew, that things would get intense...
During the session, i was strapped to the kneeling-post with the shock-collar on my thigh and the estim-device connected and had to recite my slave-mantra while She shocked me, stretched my nipples and brought me close to the edge repeatedly with the estim... I had a hard time to concentrate on the mantra and i mixed up the sentences more often than i got them right...
Half through the session, i noticed that one clamp started to slip off. Ouch!!! But no need to stop, since the other one was still on.
By the end, She was shocking me non-stop and the remaining clamp was pulled hard, but it held...
When She released me, i first didn't notice, how exhausted i was (i was sweating) and how sore my nipples and knees were, but i feel that today...

Lady Helena has exquisite taste as to her choice of fun. :twisted:

And quite an admirable mean streak..,. :whip: 8)

Oh yes, She can be mean, but i love Her style... She had told me that She would torture me harder the more i screamed, but with the shock-collar, there is no chance for me to keep quiet...
i still feel a little sore two days later...

My experience is that clover clamps will pull off.

I recommend something elastic between the clover clamps and the puller. A good heavy duty rubber band works good, but they degrade quickly over time. A steel spring will remain the same but is a bit more bulky. Rubber "O-rings" don't degrade very quickly and can be quite strong . . .

My experience says so too, but not without some pain - both before and after coming off. :shock:

A good gag is recommended if your dungeon isn't well soundproofed. :mrgreen:

It's intended that the clamps can be pulled off...
My first try was with a servo-motor, but it wasn't strong enough, so it kept slipping back, then tighten again, slip back, tighten...
Also interesting, but not what i was trying to achieve...
