MECHANIC VENTILATOR COVID 19 LOW POLY. STOP - DO NOT PRINT! MECHANIC VENTILATOR WAS REDESIGNED - https://www.thingiverse.com/thing:4252113 THE 3D PRINTED PARTS ARE NOT WORKING PROPERLY! I WILL CREATE A NEW DESIGN USING 8MM LINEAR BEARINGS. I WILL Dismantle ONE OF MY OLD 3D PRINTERS, AND REUSE THE PARTS FOR THE NEW DESIGN. STAY SAFE! MECHANIC VENTILATOR - Use your own judgment for these last resort solutions! UPDATE: 29 March 2020 - I HAVE ADDED A STRONGER VERSION FOR THE SHAFT ASSEMBLY - Version C. CURRENTLY WORKING ON A SYSTEM TO SECURE THE BAG IN POSITION. UPDATE: 28 March 2020 - DUE TO TWO FAILURES DURING SHAFT PRINTING, SINCE CONTACT SURFACE BETWEEN PART AND PRINT TABLE IS TOO SMALL, A NEW VERSION WITH A SACRIFICIAL BASE WAS INCLUDED, SHAFT IS STILL UNDER 200mm! On version "B", two sensors can be installed using the threaded bar as support - OPTIONAL! ALL PARTS CAN BE 3D PRINTED. ALL PARTS ARE DESIGNED TO PRINT WITHOUT SUPPORT. ALL STL FILES ARE IN THE RIGHT POSITION TO BE PRINTED. IT USES A NEMA 17 STEPPER MOTOR, M4 STUD BOLT 6-8MM AND A M4 NUT TO CONNECT THE MOTOR TO THE SHAFT, AND 4 X M3 6MM COUNTERSUNK BOLTS TO CONNECT THE MOTOR. 4 X M4 16 -18MM BOLTS + NUTS FOR BASKET-ARM 4 X M4 16 -18MM BOLTS + NUTS FOR BASE - IF SECURING THE UNIT TO A TABLE, SEE THE THICKNESS OF THE TOP FIRST! SHAFT THREAD HAS A PITCH OF 16MM - DOUBLE END THREAD. SHAFT MOTOR HOLE IS OFFSET WITH 0.3 - THEREFORE HOLE IS 5.6MM IT HAS A SUPPORT FOR LIMIT SWITCH ON EXT. END "B" VERSION SECURES THE THREAD ASSEMBLY WITH 4 - 220MM - M6 THREAD BARS (16 - M6 NUTS AND WASHERS) THIS MACHINE WAS NOT TESTED AND WAS NOT MEDICAL APPROVED. USE IT AS A LAST RESORT! BE SAFE! STAY SAFE!
