Description

The Design

You Asked for it, its here!

The new Stackable impossible passthrough!

Fully compatible with the V2 Series,

The “male” part of the thread seems to defy physics by passing through the slightly larger “female” Part

Now your can print as many tall parts as you like and add them together to make an extra long vortex tube!

The Ball Twists its way down the Tube

There is a Top cap and a Bottom cap to prevent the the ball escaping

Or, if you've got a spring from a ball point pen lying around, try adding this into the centre!

Dimensions of 1 tall part is approximately: diameter 32mm x 60mm

Let me know if you experience any issues.

If you enjoy this print consider giving it a boost (It'd really help me out!)

Never Needed, Always Appreciated!

Printing

Ensure Auto Tree supports with 30 degree angle is used (to support the top section of the tall piece)

The ball is “floating” to ensure the best lower surface possible. use auto tree supports to an angle of 30 degrees

It is set up to print sequentially, it is very tight on the print bed, if you have any issues i suggest you split into separate plates.

Once printed let the build plate cool before trying to remove.

My Work

After many years in Engineering, I've just decided to try and follow my childhood dream of becoming of a Creative Designer.

A Creative Designer of what? No idea! Right now I really like puzzles, mechanisms and kinetic sculptures so that's where I'm going to focus my efforts.

I printed this at 350% for giggles. I love it. BOOOOSTED

Dunno what I was thinking! lol I added one.

@RedLacePunkFace

whoa! I need one like that! Is printing one that size as simple as just rescaling or are there settings that need to be changed?

@thegreatgoogone

balls don't fit.. I've tried 100% 97% and 95% on the ball size with luck.... really sad

The designer has replied

@RJDesign

Hey, so scaling won't help because of the geometry, could you try running flow rate calibrations and printing again?

@pcmomof6

mine was the same

@user_1817045873

I'm sorry, but you have a faulty model. The ball inside is not hollow, which is why it does not pass. Please correct this misunderstanding

@benjamin.whitle

Need some help here. No matter how I print it, after I join the two halves, the ball won't slide form one to the other. I can get it to go through if I offset one a little, but then they won't join using the notches. Ideas?

The designer has replied

@RJDesign

Have you got a picture so i could have a look? the guides should line everything up nicely

@Mqrius

Replying to @SaiLentKnight :

The offset is not a model issue, rather the issue is that the top and bottom surfaces of your prints can't get close enough together. Are you guys printing on textured PEI? That adds ~0.2mm of thickness to the bottom surface because of the surface roughness. Try sanding down the bottom surface afterwards, or just cut 0.2mm from the bottom of the model before printing. @SaiLentKnight the rotation between the notches you're pointing to is not a flaw, that comes from the rotational movement of the model. If you can get the top and bottom surfaces completely flush without that 0.2mm problem, then the notches line up too. But you have to assemble the two towers before adding a ball. Edit: You could also have over-extrusion. Anything that makes the top or bottom surfaces not completely flat will cause this issue, but in any case removing a few tenths of millimeters from the bottom surface fixes it. @RJDesign maybe there's a way to have this be less reliant on perfect prints... Maybe if the second tower sits on little pegs instead of needing a completely flat surface? Not sure.

@RJDesign

Replying to @SaiLentKnight :

Looks like you need to click them together. the smaller part should sit flush inside the inner. Picture of correct and incorrect attached (the one with the ball is incorrect)

awesome profile scaled to 350% as well.

Thats Huge!

@8BitTitan

Did you need to change any XY or just do a straight scale up?

@armyrcer

Replying to @8BitTitan :

just scaled up

Prints awesome in PolyTerra matte rainbow. You gotta force it back and forth a couple times before it'll start easily sliding through the part where two towers join. Once it's broken in, it's amazing.

@CrownWalker

Wow that is a beautiful color, Good choice!

@RJDesign

Brilliant Colours!

Replying to @user_1817045873 :

I'm not sure what you mean? As far as I know, thousands of people have successfully printed this file. What exactly do believe the problem to be and I'll try to help

@Rickstoyroom

I cant get this to work after printing it the ball gets stuck and wont drop..

The designer has replied

@RJDesign

Hey, it looks like the overhang at the top is a bit too rough for the ball to pass through. It can be a difficult area to print. If you'd like to try again I recommend making sure your filament is dry and perhaps even slowing down around this area. Hope this helps

really neat print!

@RJDesign

Looks Great!

@zwometer

The print profile is no longer public

Looks amazing, especially if you have some multicolored filament. Sadly the supports lead to some jagged sections where the ball gets easily stuck. Will try to sand them down. Maybe use PETG as support interface material?

(Edited)

@RJDesign

the roughness shouldnt be too bad, maybe run one in a different filament just to see? you can always add it into the stack

@jasondelly100

well im sorry about that
