recycle failed 3d Print Shredder

thingiverse

Will update when finished, box box and hoper are now built, next is to think of a way to add a gear motor with chain drive. IF ANYONE NEEDS EXTRA PHOTOS THEN LET ME KNOW WHAT OF AND I WILL POST THEM HERE. Also i still have the tinker cad files and am willing to give the link if any one needs to adjust anything. We had printed and built the compost shredder we’d seen on Thingiverse which had been put up by THYMARK It worked reasonably well, but there just wasn’t enough “beef” to it for our “wants”. Casting around a few ideas and we came up with a new design that would give us more power. We decided to add a gear motor with chain drive to the grinder. I went to Ace Hardware and got a 3/4 rod for $15, some square tubing for $5, and gears on eBay for $8 each - so four of them were $32. I also picked up some Helicoil inserts for $5, and an 8ft length of iron wood from a local family-owned store that knew what they were talking about. The other bits we needed were printed. There is welding involved, so if you're not comfortable with welding or cutting then PM me and I might be able to help. The shredder spacer STL file is a template only, the rest is up to the builder. Some tools needed are a grinder, a welder, skill saw or band saw (preferably both), and a drill press. The total cost was $60. The gear motor with chain drive works great, it gives us more power and allows us to grind thicker items without straining our drill. Tooth size varies between 82 and 85mm, x and y, and z is 20.0 to 20.5mm high. Bearing side plate dimensions are 16mm x 90mm x 160mm. Four ball bearings - SKF 6006 ZZ or 2RS are needed, as well as a Helicoil kit 5/16 or metric equivalent plus bolts, and a bunch of 3/4 nuts and washers. Some parts from the compost shredder project are also compatible. Added to the STL files are templates as well as full prints so depending which way this is made then not all files are needed. Needed STL files are four bearing spacers, two bearing sides, same number as teeth spacers as cutter teeth, and the shredder spacer STL file is a template only. The rest is up to the builder. Some tools needed are a grinder, a welder, skill saw or band saw (preferably both), and a drill press.
