My Adventures in 3D printing

Heya!
This will be a little journal thread, where i'll be posting some stuff i'm working on, what troubles i run into or what i learned on my 3D design and printing journey.
So let's start:

Today i finished the first prototype of my own device, printed with ABS filament.
It's basically a cage device with an added belt.
Got kinda inspired by the CS-100 belt, but i have some issues with my own CS-100. So i began to plan a device, that could work for me.

And that's what i came up with so far:

The lock works pretty much like the one on the CS-100, but i put it below the bolt so more material is surrounding it.
I figured that would be more stable in a 3D print.

Once worn i noticed, that the tube is too long and its profile creates a noticeable bulge in my pants.
And sadly the second lock snapped of, because the layer adhesion wasn't good. Well... it isn't neccessary, but could have been a nice addition.

ABS seems to be kinda tricky to print.
I had an issue with the adhesion between the layers. The begining of the tube seperated where it was connected to the locking mechanism.

Luckily this could be fixed by welding it back on with acetone.

So i made a second version today, which will be printed over the next weekend, where the tube is more tilted towards the body and is about 1.5 cm shorter.

For the print, i try maxing out my printers nozzle temperature at 250°C and disable the print cooling fan.
This should lead to the layers sticking better to each other.

P.S.: My printer is a "Anycubic Kossel Linear Plus" delta printer. Which seems to be pretty good for its price of 270€!

 

It turns out 250 was too hot for the brand of ABS i use. I got some burned spots in the plastic.
So i went back to 245°C, but shutting the part fan off did the trick.
The layers now stick pretty well.

Was thinking about moving to PET-G too, but i want to print chastity devices i can use, not just prototypes.
ABS can be smoothed using commonly available actetone to get smooth surfaces.
With PET-G i wouldn't get a surface that smooth, which could cause chafing when wearing the devices.

But i agree, for prototypes and things that don't need to be completely smooth on the surfaces, PET-G is the better choice!

And about the enclosure. Well... I'm not experienced enough with 3D Printing and CAD yet to design a durable cage having the shape the tube has.
But that may become my next project, after i perfected the tube design. ^_^

For an update on my project:
I finished printing version 3 today and am wearing it for a test run at the moment.
In version 2 the tube was too close to the ring and pinched some skin between the tube and the ring and the tube was still too long.
So i put a bit more distance between the tube and the ring and shortened the tube some more.
It seems that i have found the length i was looking for and the pinching problem is gone too.

Tomorrow i can tell, if it's wearable over night or if something breaks or damages the skin again.

 

I guess, i'll try PETG when i used up the ABS.

After some busy weeks, i finally had time to work on my design again.
Next iteration is making it less enclosed for better hygene.

I hope my printer is able to print this...
Maybe if i flip it, so the front is facing down and the support from below is able to stablize all the holes rather printing them as overhangs.
Gonna find out the coming weekend.
