Default What do you think? Plastic air filter adaptor

http://www.thingiverse.com/thing:1832430

I'm printing this today. I find it very interesting, perhaps the plastic may work on a predator. I guess we shall see.
I'll be using this filter: https://www.summitracing.com/parts/u...EYoRoCjcbw_wcB
instead of a cheaper one because it has the pre-filter and everything.

Printing intake adapters could save us money. I could print a ton of these and give them away for a few bucks.

I'm printing this part with ABS instead of PLA. ABS is stronger, not biodegradable, and withstands over 410 degrees Fahrenheit.

How much are you going to sell them for ? If it works. You might want to make a crow foot wrench shaped metal piece so it doesn't vibrate to death around the bolt holes.. Just thinking out loud..

Shipping for me is like $3-$4. With material costs I could ship out the parts for $10 each, free shipping, for members here. I don't like making a ton of profit off people unless there's a huge demand. Since adaptors and air filters together run at $30-$50, being able to use this and a cheap filter or a scooter filter that you can get from just about anywhere makes it much better in my opinion.

Well, it's working with ABS. But, I had some settings off so I scrapped the first print and I'm trying again.

Even better, a finished one!

This took exactly 3 hours to print. I broke off the bottom 1/4" of it by accident (pulling these parts off the print bed can be tough, especially with the flat surface that was printed around it to hold it on during printing).
I don't think it will have any trouble bolting on still.

I printed it to be 90% solid. And it is SOLID. The part where it broke was when I opened the printer door and let cold air in, lessening the integrity. This is one of my first time since printing with ABS so it took a bit of T&R.
I'll test fit it soon. It's pouring rain on the two feet of snow outside and I really don't want to get soaked right now to get to the workshop.

This predator happens to be going on a motorized bicicyle that will be more like a motorcycle. I'm going for this style on a cruiser frame:

Edit: Incredibly, someone has made an entire 3D model of a Briggs engine. I could theoretically print any piece of this I desire. https://grabcad.com/library/briggs-a...-4-x-2-27-64-1
I have also found a second model of air intake: http://www.thingiverse.com/thing:935416
I will print this next and see how it looks.

This is very interesting. If you could print up an adapter to run a mikuni pz30 on a predator 420 I would be interested

@ Rail Rider, and, well all of you,

The problem is you need a 3D model for any new part. I have not learned any 3D modeling but I could whip up some designs with a little time and effort. Also, I only have PLA and ABS plastic, so different types of plastic cost $ to get a whole roll of material. https://www.google.com/aclk?sa=l&ai=...IzwIwBA&adurl=
Polypropolene happens to be the most expensive ($50 vs $20). A little less expensive are %50 metal and %50 wood filaments. If I had a business, I'd keep stock, but I don't have a business. Just a hobby printer and about 7 rolls of the more affordable, reliable, and most commonly used plastic.

So all of these things must be considered. Personally I see no difference between ABS and polyprop. Nylon, however, is very different, as well as ninjaflex with is a stretchy rubber. Besides those two, plastic is plastic.

I'll see tomorrow if I can model some adapters for the mikuni. I have absolutely no measurements for the predator 420, but, that's what google is for!

A little more on plastics:
"ABS has a tensile strength of about 5500 psi, while polypropylene has a tensile strength of about 4000 psi. ABS is also comparatively harder and lighter. So it's fairly obvious that ABS is the stronger material out of the two." - Quora

---------- Post added at 01:23 AM ---------- Previous post was at 01:20 AM ----------

I look around on websites that have, basically, libraries of free models. Isn't this useful: http://www.thingiverse.com/thing:1649639
When I need to design parts myself, which looks like now, I will.

Can you re-scale a download file m.yeggi. Com has a file but it is to small .

I agree a 22mm adapter would sell well. It wasn't hard for me to make mine out of steel but plastic would be better due to the heat transfer effect.

Comming from an injection Molding background... I find it interesting that ABS is cheaper then polypropylene, understandably cheaper than PC, acetal or nylon.
Maybe the prices have changed... But poly should be the cheapest... ABS is at least an engineered material if not somewhat...

If you had an extruder... One could mostlikely talk to a local molder about getting a few bucket fulls of material for cheap... Or mostlikely free... Then make all the filiment you want...

The higher volume guys are the guys you want to try to ask... Also the small guys are more likely to hear what you are doing and also might be interesting in your work aswell... Maybe together as prototyping is expensive...

Yeah Iagree about the pricing and whatnot. I don't have an extruder but I really wish I did. The cheapest ones are about $350 which is kinda expensive to me.

I think I have seen people make them for less than $100.. If you are good at scrounging...
Major buy is the heater and controller... Can get them for 120v... Better 220v...Then the screw motor...

The barrel and screw, are just a pipe that fits closely to a large wood drill bit...

So, I test fitted the first model. If I didn't break off that bottom piece it would have fit without the nuts running out of thread...
anyway here's some pics. I finished the second model and it's perfect. Fits much nicer too. The second model is in the last two pics.

One thing I think I Like about that, is there is a Connection for the valve cover pressure relief hose.
However... Usually this hose goes to the Air box where any oil is caught in the factory Foam oiled Filter.
That model you made will allow excess oil directly into the Carb.
That could be a problem depending on the amount of oil.
