Cheap Plastic Shredder

cults3d

Cheap way (well comparably...) to get a plastic shredder, building it from an Amzaon 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) It works! See the notes at the end... This project is inspired by similar project using the cheaper, smaller brother of that shredder (but having heat problems than). Cant't find it anymore, so thanks to anonymous :-) Going through the simple steps you end up with a plastic shredder, wich can be changed back to an almost unchanged paper shredder within 15 minutes. So let's go over to the photos. At the 2nd picture, you see shredder with removed bin holder. 3rd: the main screws (6 of them) are somehow hidden and deep sunk, you need a long tool to reach them. The one in the picture is to short... 4th: but this one did the trick. 5: you see the backside of the cover with srews already removed. Fingers pointing to where the light sensors was. Just remove all the screws in the marked area. Put Lightbarsensor and it's led where they do not see each other (I did not cut them off). 6: with all those screws removed, you can remove that silver colored front panel also. Keep it somewhere. 7: Do the cut out. I made it so that two of the outer screwholes remains (It's 170mm wide and covers the whole plateau wich 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 do not 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 Light bar pieces in a way that the shredder do not eat them up. 8: And you can put the silver panel back there. Than again, you have back an ordinary paper shredder, except that it is always running, not only when you place something in there as before. 9, 10, 11: If you remove only half of the lightbar 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 it's original place, than you have back your Paper Shredder almost as it was before and with the same functions. Last picture: The biggest piece the shredder could cope (took a while) with and the shredded material after the first pass (I fink giving it through two times is enough, but best is using a sieve). If you can 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 it's limits with massive pieces, but most builds will eaten 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 childrens. Can you make filament from it? Yes, but... I could make some filament with the shredded plastic. and a filamaker. I build 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 to narrow hopper. But it works horizontally.
