Made my first batch of one-way valves. I encased them in plastic tube (carefully using Aquaseal to bond them) to ensure that the hinges don't get gummed up when siliconing them into the bottom of the seat scupper. Some of these are on their way to Mickeymouse, but I am happy to make more if anyone wants them @$A20 a pair including postage(that's about $250 US I believe :lol: )

As an aside... about three months ago, I split one of my ST Turbo fins from the top down 4 inches. I used Aquaseal to glue it back together and they are still working perfectly, even though the mast is visible. Aquaseal is designed to repair wetsuits, so it is extremely tenacious but flexible.

I'll have to look into this. Got some other projects on the go at the moment...

This 3D printing technology is getting better and better. They are way more reliable than paper printers, but I suppose that isn't really saying much.

From a rough sketch, to modelled and printed in 5.5 hours.

G'day Slaughter,
Mate, that's very impressive :shock:
Is it just an optical illusion that your printed part looks smaller than the original?
Did you print this with an exotic 3D printer, or just a home garden variety?
Cheers

Very interesting thread! Funny thought I had the other day:

I just bought a house that is a bit older and more accommodating of outdoorsy decor than my old place. I wanted to get a carved wooden sea kayak to put over my fireplace, but I soon realized that they were a bit difficult to come by. (Also, if you're not familiar with real wooden kayaks, they are extremely beautiful: http://laughingloon.com/). I started looking into the proper tools and skills I'd need to acquire for carving and staining my own wooden kayak model. As someone who sadly doesn't work with wood a whole lot, it was a bit daunting.

Then I had a thought: it would be really cool to have a model of the boats I currently own, and since they're made of plastic in real life, why not just get a 3D printer and some CAD software and print connectable sections that I can hand-finish? (Clearly this is getting away from mantle-piece territory and into moonshot brainstorming). At that point, a 3D-printed Adventure Island model seemed within the realm of possibility. I'm a software engineer, so naturally that means I'm automatically good at anything to do with computers (not really... CAD software is a beast). Print several pieces, connect them together, add some black string, a vinyl sail, etc... Maybe paint the body afterwards to give it a smoother surface and vibrant color.

Fast-forward, and I've settled on a 3D printer and trying to calculate how many custom kayak models I can sell to people in order to pay off the price of the printer. :D I'm also considering the ramifications of the Hobie vs bicx lawsuit after selling scaled models of their boats.

This is a typical evening for me. It will probably never happen, but I'm still tinkering with the idea. A custom 3D-printed model of my AI on my desk (maybe not on my mantle) would be pretty sweet.

That is amazing Slaughter. 8)
I can see this becoming very popular as the printers get more affordable.
Do you need to have a good knowledge of CAD to get to the final product?
How easy would it be to 3D print this?

The epoxy failed on our recent week away and I had to bodgie up a hiking stick alternative.
I guess it's a steep learning curve?

Hey ya Mike. How's it going mate. Yep it's an optical illusion. The parts just held up to the computer screen. This is all work related. The printer is a top of the range one but items like this can be easily done on the garden variety.

Bicx - never thought of a model Hobie .......hmmmm. Lotta work though. Maybe in retirement.

Stringy - strength of the part may be an issue. Dunno. We have a CNC 5 axis mill on it's way and may need small parts like this to test out. :wink:

Jees Russ, I really hope the bast**ds don't cut your funding!

Stringy,

you might be able to use a product like 123D catch (do it from your phone) to take pictures of the object, then something like tinkercad or 123Dmake to finish it off. Catch has gotten a lot better, but the shiny parts can still be problematic.

I've used this technique for making a couple of things, but not for a kayak part yet. Right now, I"m working on a "false bottom" cover for my transducer. first modelling it out of clay on the bottom of the hull, then using catch to capture it, then finally doing some hollowing and printing on a MakerBot.

Full disclosure, i work for Autodesk, Inc that makes the above products.

Fingers crossed Tony.

That's really interesting software Steveo. Might look into it a bit further to see if we have an application for it at work.

Thanks Stevo, there's some great info there. I'll spend some time looking at that software in more detail.

if nothing else, its fun to get a 3D print of your head.


123D in google search will get you to the full suite of products... i use mostly tinkercad and catch. My daughter loves using Sculpt, then we print her creations...

Hey all. The 3D printing world is changing fast. Lots of new materials. I bought a bigger printer earlier in the year. Also been playing with nylon. It has it's own interesting issues but you can get some mighty strong prints.

As an alternative to 123D, search for "structure from motion".

This is a good starting point for some software -

VisualSFM : A Visual Structure from Motion System http://ccwu.me/vsfm/

This has turned out to be a really informative 'off topic' thread CGM.
You are such a rebel.
