K-Cup DeTopper

thingiverse

Tool to cut the tops off K-Cups for recycling. There is still a small plastic ring on the aluminum top but far better than tossing the whole K-Cup. Uses a standard razor, an M3 nut and screw. 3/9/2017 - Added new version which places the Blade 1mm higher. Fixes an issue where some k-cups were glued to the sides and tore when being opened. Post-Printing Step 1: Print I printed with supports enabled in Cura. I'm not sure if printable without I didn't chance it. Step 2: Remove all support material I scraped out the support material with a small screwdriver. Step3: Insert nut I press fit the M3 nut into the bottom with a pair of pliers. Fits snug. step 4: assemble Assemble the whole thing and tie it together with an M3 screw. (I only had 10mm screws. You could likely get away with 5mm or smaller." step 5: Adjust blade and tighten Adjust the blade till the required about of blade is sticking out. I used the full available length, but my razor blade was very used and very dull.
