Bill of materials
18 pcs stainless steel blades cost $50
Other parts are made by myself or Recycling on old machines
Frame uses CNC engraving machine to cut 10MM PVC sheet;
16MM hexagonal steel shaft;
6003 inner six corner bearing;
30:1 worm gearbox;
200W hand drill;
Wooden base;
The shredder in this video is just right,
But it can't crush larger plastic,
It uses PVC plate as the bearing seat,
It will break under more powerful conditions, so steel must be used.
The old worm reducer in the video can't withstand the greater torque either.
The blade must be sharpened to reduce motor power.
There are still many areas that need improvement.
Want to get a reliable shredder,
The actual cost time is much higher.
If you want to make it , I recommend you watching my videos playlist .

No way this could be a $50 DIY. I have been looking to make a small shredder for some time now and its $50 just for a shaft and other small parts. This machine must be the size of a coffee cup..

no way can you build that for $50 . the gear reduction drive is more that 50. the cutout steel teeth our more than 200 the steel frame 50. the gears and bearings. said enough

[@tasmanianbadger]

Michael Hursh... what steel frame? It was a wooden box with some screws. The steel teeth and spacers were 3mm washers that someone shaped with an angle grinder or bench grinder. The gear reduction drive is a valid point... though I suspect that the people looking to make a home made shredder are more likely to be competent parts scroungers than the average joe. That said, putting a price on it was counter productive.

[@TheRebelmanone]

You can buy his blades for $50 and get his free download for the 3D print. You get the shredder blades for $50 and the download free. So go find a used gear box or something for free, then it will be all for $50. Get with it, like he don't know motors and gear boxes cost money.

[@leebrewer1190]

Being taught HOW to think is something the education system does not do anymore. This is why people have trouble understanding how this shredder only cost 50.00. Hint...the word "salvage" will open up a whole new world to people who have been victims of the public education system.

[@JeffDM]

@@tonycstech That doesn't explain the alleged cost of this design. This looks better for breaking up plastic than any paper shredder than I've even seen. Even paper shredders that can cut CDs jam pretty readily on printed plastic parts. I spent over $100 on the heaviest duty personal paper shredder I could find. I had to quit using that because it didn't do the job.

I am in desperate need of information that online ai ebay and other are absolutely no help. First i know there are many variables but i need sone place to start. I need a gearbox to hook up to a small shredder designed for a hand crank. I want to hook up either a bema 34 stepper or servo of which i have each. I also have a 2 hp “1500kw” servo. Lathe and mill to adapt motor to gearbox but i just have no idea what gearbox i need. Saw a video that was using to planetary and stepper but no info on gearbox. I need a model ir something to start looking at. I can get scooter gearboxes snd other i just beed some idea. How much torque do i need for shredding 3d prints

Why do you mix colors? These are Laser-cut discs, right? OK, 18 discs, at least $1.50 each, is $27... How do you get all the other stuff for under 23 Bucks (scrap parts included)??? I've got a paper shredder, when I take the motor and the cutter of it, do I have a ABS/PLA/...-cutter for free? What does the Gearbox normally cost, and what about the motor (drill)?

[@nofluffDIY]

I'd like to suggest a simple product idea that I think can be successful for all small-scale plastic recyclers, and I'll be posting it to all the channels I watch: make flat, disk-like platters that can be placed around common-sized property fenceposts, to prevent vegetation (weed or grass) growth at the posts themselves. Various designs can be considered such as a disk with a slot/hole in the center and a simple slit from center to perimeter; or a 2-piece design that overlaps approximately 45 degrees, so as to both make fabrication simpler and prevent vegetation grow-through. Center holes could be made variously for round wooden posts, approximately 12 cm/5 inches... or rectangular approximately 4x8 inches for concrete posts. I volunteer at a horse farm and they mow their fields, trying to cut closely to their 500 (?) posts but have to spend more fossil fuels both cutting more tediously AND following up with hand-held trimmer tools. This is an ideal market: outdoors like so much recycling already; low specificity/quality demands; and it turns waste into a CO2-reducing solution. Consider this comment, defining the conception of such products, a release of any claims of invention/patent on such products, whether full-circle or overlapping. There are some products on the market but none seem to be simple or cheap. Maybe one of the prominent recyclers who already have ecommerce set up can be an aggregator who facilitates the direct shipment of the product from many producers.

If this product is to be exposed to the sun then it's unlikely to last long, unless it's UV-resistant?

[@diychen]

Hello, I'm selling some parts on eBay www.ebay.com/usr/cnnewcrz-9

[@EvenTheDogAgrees]

@@diychen Oh, look, the supposedly $50 machine costs $370 without motor, excluding shipping. Bit of a nonsense clickbaitey video title perhaps?

[@diychen]

@@EvenTheDogAgreesDo you know what DIY means? ? The cost of retrofitting with old items, Can it be the same as selling a product with various costs?

[@diychen]

@@EvenTheDogAgrees I have shared the drawings for free, You can make it yourself, you should thank me! I didn't ask you to buy in the video! !!

[@EvenTheDogAgrees]

@@diychen Then perhaps you should not mention the cost in the first place. Depending on what you may have laying around, and which machines you may have access to, your costs could range from $0.00 to a couple hundred. So it's pointless to mention the price unless we're talking commonly available parts you can buy new, and for which you'd preferably provide a price breakdown in the BOM. The only reason you'd mention that ridiculously low price is to attract views, aka clickbait. If I have to buy a paper shredder for the blades, the cheapest one comes out to about $48. And then I still need to get a gear reduction so that the puny motor has a chance of chewing through the material, and some sort of case for the thing to sit in. As others in various threads have already pointed out: the cost of the gear reduction alone is a couple hundred, yet somehow you maintain that this can be made for around $50? Does math work differently on your planet? And yes, I know what DIY means. It has nothing to do with retrofitting (which means adding new tech to old items), nor using old/used items (that's called "recycling"). It means "do it yourself", and is most often done with new materials bought at the hardware store.

[@DennisKenneybees]

$50 is complete BS. Just the blades run $5-10 each on Alibaba, and those are the cheapest of cheapest. Then you need to get spacers from the same grade of steel.. not cheap. Other than that, thick hex axles aren't just thrown out on every street corner, and gearboxes don't fall from the sky. Complete clickbait. Even the CAD simulation runs the machine in reverse, they just don't care about accuracy.
