Cheap Plastic Shredder

Here is the rewritten text: You can get a plastic shredder cheaply by converting an Amazon Paper Shredder (https://www.amazon.de/AmazonBasics-Kreuzschnitt-Schredder-Bl%C3%A4tter-Papier-Kreditkarten/dp/B01LXANKY3/ref=sr_1_fkmr1_1?s=officeproduct&ie=UTF8&qid=1545745601&sr=1-1-fkmr1&keywords=amazon+basics+schredder+f%C3%BCr+18+bl%C3%A4tter) for a fraction of the cost. It works amazingly well. See the notes at the end... This project is inspired by similar projects that used a cheaper, smaller brother of that shredder but had heat problems. Unfortunately, I couldn't find it anymore, so thank you to anonymous! Going through the simple steps will give you a plastic shredder that can be easily converted back into an almost unchanged paper shredder within 15 minutes. Let's take a look at the photos. The 2nd picture shows the shredder with the bin holder removed. The 3rd picture reveals the main screws (6 of them) hidden and deep sunk, requiring a long tool to reach them. The one in the picture is too short... But this one did the trick! You see the backside of the cover with screws already removed. Fingers pointing to where the light sensors were. Just remove all the screws in the marked area and replace them with Lightbarsensor and its LED, making sure they don't see each other (I didn't cut them off). With all those screws removed, you can easily take out that silver-colored front panel also. Keep it somewhere. Do the cutout. I made it so that two of the outer screw holes remain (It's 170mm wide and covers the whole plateau which was covered by the silver panel). You can fix the two self-printed parts with them After that, you only have to print out the 2 STL pieces. The funnel is very big, just sink the part you don't need through the table (put it upside down to print without supports) when setting up your print. Glue the pieces together if you think that's necessary. Screw it to the cover, reassemble the parts. Store the two Lightbar pieces in a way that the shredder doesn't eat them up. And you can put the silver panel back there. Then again, you have back an ordinary paper shredder, except that it is always running, not only when you place something in there as before. If you remove only half of the light bar as in the picture and if you screw the cutout against the silver Panel, screw the Panel against the remaining screw holes, put the light sensor part under the blue tape back to its original place, then you have back your Paper Shredder almost as it was before and with the same functions. The last picture shows the biggest piece the shredder could cope (took a while) with and the shredded material after the first pass (I think giving it through two times is enough, but best is using a sieve). If you can, use a garden shredder to take care of the big pieces, this is the perfect complementary fine shredder. Of course, you can bring this shredder to its limits with massive pieces, but most builds will eat up very well without much noise or heat. ---------------------------------------- This thing has no emergency stop button. So add one and mind your fingers! Do not use it on hamsters. Keep it away from children's hands. ---------------------------------------- Can you make filament from it? Yes, but... I could make some filament with the shredded plastic using a filamaker. And I built a sieve of 4mm to sort out what needs another passthrough (After 3 passes, 60 to 80% will be fine enough). But making filament from it seems to be another story. It's gliding much worse than the brave round pellets, so there need to be adjustments. For instance, my vertical mount does work well on pellets, not on the shredder stuff - guess it's the too narrow hopper. But it works horizontally.
