$50 DIY shredder to Crush recycling from 3D printer parts ABS or PLA

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 .

I'm skeptical about the total BOM of this being 50$

very cool!!!
thanks!!! more video please...we in Russia really have a lot of garbage with plastic. and getting rid of problems is simply awesome !!

Thanks, I bought the STL files! Bravo.

Chen, this is a nice work! thanks for taking time to document this.

A custom designed sieve/sift would prevent the hassle of having to reload the machine over and over again for finer grains of filament.

maybe $50 if you print your own parts. Try adding a mesh in the bottom to only allow small particles to drop out. Less times for re-feed.

This channel is $50 click bait
And we can't even dislike it anymore.

[RixtronixLAB]

where did you buy those "18 pcs stainless steel blades cost $50" ?thanks

[onionface]

If only there was a way to let other people know this video is click bait.... hmm, something like a thumbs up, but the opposite.

Genial, gracias por compartir un abrazo desde argentina 🇦🇷

$50 only if you have access to a waterjet cutter, but you likely don’t and minimum about $150

[MrManta]

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

[peterbirrer]

Hi nice Project. i wonder how much force there is to crush the plastic. the gearbox is 30:1, but what does your motor provide?

BY CASUALITY YOU WILL STILL HAVE THE PLANS AND MEASUREMENTS OF THE PET MILL AND HOW CAN I DO TO GET YOUR MEASURE, I LIKE THE MACHINE NOTIFY ME

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.

goooddd!!!! fine!!! muy buen video!! saludos desde argentina

[toneandersen]

Can this be made a little bit bigger? I would like to recycle plastic bottles etc.

[umgarbort]

con la malla circular ya no tienes que pasar lo molido 3 veces

[Nevicica]

Please can you try a piece of fabric and a piece of a yarn sweater?
Those shredders are like minimum 600 euros!

1What is the name of the part that fits the drill?
Which in the project is in yellow
