juice squeezer
Description
###The Story: When Life Gives You Lemons... ...Print An Electric Lemon Squeezer. It Actually Started With A Big Sack Of Oranges I Bought On A Budged A While Ago. They Were Too Much For Me, So I Decided To Make Some Juice. But There Was No Squeezer. Obviously This Is One Of The Ever-Growing Number Of Problems In Life That Can Only Be Solved With 3D-Printing. ###My Goals: * 1: Design A Squeezer For ~1/2L Of Juice * 2: Make It Motorized Because Why Not? * 3: Use A Graceful Way To Activate The Motor * 4: Make It Reproducable (E.G. Only Use Widely Available Standard-Parts) * 5: Don'T Kill People With An Extremely Unsafe Design * 6: Make It Look Fancy * 7: Make It Printable On A 20Cm Buildplate * 8: Make It Simple This Resulted In A Design Based On Cheap And Very Simple Ktyz50 Motors With A Sophisticated Translation Based On Inner/Outter Gears. I'Ll Upload That One Later In A Series Of Failed Designs (But I'Ve Added A Rendering To The Images List). Why "Failed"? This Motor Just Hasn'T Got Enough Torque For This Job... Probably I Should Have Done The Math Before. So This Is The Second Attempt With No Gears At All But A Rather Strange Activation Mechanism. ###Goals Achieved: * 1: Check, It Easily Fits 2/3L Of Liquid. But Better Empty The Bowl After 1/2L For Safety Reasons * 2: Check * 3: Check * 4: Check, But It'S Rather Expensive * 5: Half-Check; It Could Be Done With Less Potential Harm But Yet I Haven'T Killed Anyone * 6: Half-Check; Actually It Looks Rather Strange * 7: Check * 8: Check; I Guess It Could Be Done Even More Simple If One Of My Goals Would Say "Cause As Much Harm As Possible" ###Before You Start: * Make Sure You Have A Soldering Iron And Know How To Use It * You'Ll Need Some Basic Knowledge About Electricity And It'S Hazards * Make Sure You Have The Equipment And Ability To Crimp Some Wires ###The Bom: * A60Ktyz Motor With ~30Rpm. I Bought This One But It'S Not Very Cheap: Https://Bit.Ly/2Qpnfmr Watch Out If Your Country'S Line Voltage Differs From 220/230Vac! * 4X Springs L=10Mm, W=6Mm. I Used Some From A 200Pc Sring Set: Https://Bit.Ly/2Vactof * 2-Terminal Biscuit Connector (Is This The Proper Term? Dictionary Says Yes, Brain Says No). Something Like This (With A Maximum Height Of 14Mm): Https://Bit.Ly/2Vc3Mso * Maybe Some Hot-Glue Or Superglue (Optional) * 4X M3X10 Screws (Any Length Up Til 20Mm Will Do), Preferrably With A Flat Head * A Power Cord With Crimped Strands (I'M Just Assuming You Have The Equipment And Knowledge Needed To Prepare That) * 4X Self-Adhesive Rubber Feet: Https://Bit.Ly/2Hidf4Y These Are Just Suggestions. You Definitively Can Have It Much Cheaper If You Spend Some Time In Sourcing Or Just Buy The Exact Amount Of Parts Needed. ###How To Assemble: * Prepare An Unplugged Power Cord With Crimped Strands * Stick These Strands Through The Motor Holder (Motorhalter.Stl) * Connect The Wires And Capacitor Of The Motor According To The Manufacturer Information (An Example For My Setup Can Be Found In The Pictures Section) * Insert The Motor Into The Motor-Holder With It'S 4 Holes Stuck On The 4 Pins * Solder A ~1Mm² Insulated Wire Of ~10Cm Lenght To The "No" And "Nc" Pins Of The Microswitch * Connect One Of The Wires To The N-Line Of The Motors Biscuit Connector * Screw The N-Line Of The Power Cord To Another 2-Pole Biscuite Connector * Connect The Other Wire Of The Switch To The Connector Of The Power Cords N-Line * Connect The L-Line Of The Power Cord To The Connector Of The Motors L-Line * If You Have A Pe-Line On Your Power Cord Just Screw It Into The 2Nd Empty Terminal Of Your 2-Pole Connector. This One Will Stay Unconnected. * Now Insert The Switch Into The "Switch-Cage" On The Bottom Plate (Bodenplatte.Stl) Until It Bottoms Out * Arrange This Mess Of Cables In A Way To Prevent Squeezing The Cables Insulation And Secure The Power Cord With A Zip-Tie As A Strain Relief. It Also Makes Sense To Hot-Glue The Line-Cord Terminal And The Switch. * Use The 4 M3 Screws To Attach The Bottom Plate To The Motor Holder And Stick The Rubber Feet On It To Prevent The Squeezer From Rotating * Lift The Motor A Little To Attach The 4 Springs To The Pins Of The Motor Holder * Now Test If You Hear A Switching Noise When Applying Gentle Pressure To The Motor * Attach The Motor-Plate Onto The Pins Of The Motor Holder - It'S Supposed To Leave No Gap * Attach That Gyroscopic Looking Pin-Thing (Aufsatz.Stl) To The Motors Shaft. Mind The D-Shape! * Now Just Attach The Bowl And The Squeezer. That'S It. ###Warning: This Is Not A Very Safe Design! Spilling Too Much Liquid Into The Motor Base Can Cause Injuries And/Or Death!!! Don'T Build This If You'Re Not Familiar With Line Voltage! On The Other Hand: Juice Is Quite Healthy. Btw: Here You Can See The Squeezer In Action: Https://Gph.Is/2K70R8B
