You could make a negative of this print and use silicone putty to make the seal. Silicone putty is harder than the liquid silicone.Pumping Now wrote: ↑Sat May 09, 2020 10:53 am Flared mouth
Can be sized to fit most any tube
I made one for a large acrylic candy jar

Re: 3D print files
A two-part project like the Monster Tube would be much easier to design and print.

Re: 3D print files
Is there a software that makes it easy to design things?
I installed Blender and freecat but I can't seem to get to grips with them.
I don't even know how to use finished files can edit (change size, etc.).
A simple software where you drag a corner of the model with the mouse to change the model.... So simple

My PETG Ball Pumping Tube
Hi Guys,
this is my selfdesigned and printed Tube. It was inspired by my bullmaster jr.
It‘s not as clean as the original, but i have a pretty good Look on the things going on in there…
Many Greets vom Germany…

Re: My PETG Ball Pumping Tube
Your print looks really good. What are your settings (wall thickness, layer thickness, etc.) and what material did you use? Greetings from northern Germanylennypumper wrote: ↑Fri Dec 20, 2024 1:15 am Hi Guys,

Re: My PETG Ball Pumping Tube
Ich habe 3 oder 4 PETG-Filamente ausprobiert. Auch das von Overture. Ich meinte aber, das das Bambulab PETG Translucent das beste Ergebnis geliefert hat. Dann bin ich einem Artikel gefolgt "How to Print HD Glass". Mit einer extrem niedrigen Druckgeschwindigkeit, gleichmäßig ausgerichtetes Infill und einer mininmale Layerhöhe lassen sich nach dieser Anleitung nahezu durchsichtige Blöcke drucken. Allerdings lässt sich das sich nicht so ohne weiteres auf die Struktur des Zylinders übertragen. Außerdem sollte die Druckzeit ca. 4 Tage mit diesen Einstellungen betragen.Pumpernorth1987 wrote: ↑Fri Dec 20, 2024 2:30 amYour print looks really good.

Die besten Ergebnisse habe ich dann am Ende mit einer 0,8mm Nozzle und einer Layerhöhe von 0,4 erreicht. Die Wände sind knapp 2 mm dick, also immer 2 Linien.

Re: 3D print files
I just started with 3d printing and cad design about 2 months ago. I use fusion 360 to design and export the files for 3d printing. For design sometimes you have to think about your shapes differently. Like to make a seal similar to the stj seal it's basically a tall rectangle with a fillet on 2 edges. There are a lot of videos on YouTube on how to use fusion.Pumpernorth1987 wrote: ↑Thu Dec 19, 2024 9:55 pm Is there a software that makes it easy to design things?

Re: 3D print files
Hi Guys,
here my latest design with integrated seal.
The dimension is similar to the Bullmaster. Whilst a bit shorter the sections for the balls is a little bit bigger..
You can download the stl at §D Cults:

Have fun !

Sketchup is free & has .stl file export to free Cura 3d printer slicer... All fairly simple.
