Custom 3D printed lily pipe

I just want to share this with everyone. I modeled a custom lily pipe in Solidworks then had it 3D printed (stereolithography). I did this because the Eheim 2213 spray bar is too long to fit on the side walls of my TRUVU and I didn't feel like cutting it since I thought there was a lot of restriction already. It also didn't help that after buying the filter, I read that Eheim over rates their filter to tank size recommendation so I think this will get really good circulation with the marginal flow rate. By the way, standard lily pipes don't fit in a TRUVU because of the acrylic border at the top so all the more reason for me to design this.

Let me know what you think.

That's super cool, I'd be dangerous if I had access to tech like that!

How much did it cost to make that? I would definatly be interested if its a lot cheaper than glass lily pipes are. I've been wanting one for my fluval for a while now,

must....have.....more....moss n shrimp!!!!!!!!!!

It was $40 on Shapeway but could've been much cheaper. I should've had them printed it in alumide. The only reason why I used SLA acrylic because it looked cool, had better part detail, and CO2 resistant (I'm running an in line CO2 diffuser. I was going to design an inline CO2 diffuser using Fluval's ceramic diffuser replacement disk.). But none of that matters really since the alumide is half as much and stronger. The SLA acrylic is too brittle. I've already had to repair it in some areas.

So alumide is aquarium safe? Co2 reistant and stronger. And it was cheaper? You ordered it online? And you drew that picture to send them to cast it out

Yeah alumide is just nylon with aluminum mixed into it. Alumide and nylon are both aquarium safe. I'm reading Shapeway's material list now an I think I would try just plain nylon first (it's even cheaper than alumide). They call it strong and flexible plastic. Yeah, you have to make a model in a CAD program. I mean, I think I can just set the model to public then you can buy it from Shapeways. They'll just print it out in 3D and ship it to you. If you're going to do that though, let me know because I need to incorporate some design changes from what I learned on this first part.

By the way, nylon and alumide is not CO2 resistant but that doesn't really matter unless you're designing a CO2 diffuser though.

How much is the alumide one? I need one for a fluval 405 not sure the diameter

And I need it so the head is in the right side of the tank if your looking at it. And the head faces the left because I still put my hoses behind the tank,

must....have.....more....moss n shrimp!!!!!!!!!!

Hmm, ok, sounds simple enough. PM me with dimensions of your tank, hose diameter, etc.

Awesome stuff, hopefully we get a few more people try materials. I could use a couple output nozzles.

Just thought I'd chime in to say good work. I use solidworks daily and use a Cube X Duo (when it works) quite a bit. Good idea!

Great idea! Now it looks like we all need to buy and learn to use a good CAD program.

Thanks. I'm glad you guys like it. Here's another version I did. The idea is to use the outflow to draw water from the surface to get rid of the surface film. Unfortunately, it doesn't work very well because of the relatively low flow rate of my Eheim 2213. I know it draws a bit of water though because when the water dips below the upper intake during a water change the outflow sucks big air bubbles through it.

Do you mind sharing the Solidworks/STL file? I have a 3D printer and it would be interesting to see if I could print one...

Going to be tricky on a 3D printer and not using SLA.

That shapeways place is cool. What kind of break in price would you get if you ordered more than one? Wonder if the price would come down quite a bit. Thanks for sharing.
