Abstract
it is an ideal for mixing samples in blood and centrifuge tubes. The 3D printed mixer is a lot cheaper than that available in market. Its almost 95% cheaper than that available commercially.
Gyratory action provides gentle, thorough mixing
- Ideal for mixing samples in blood and centrifuge tubes
- Fixed speed and pitch
- Safe for cold room use
Materials Needed
- M3 16 mm screws and nuts : 10
- 12 V dc motor : 1
- Roller skateboard bearings : 2
- Eraser : 2
==Items to 3D Print== all STL files are available here " http://www.thingiverse.com/thing:1195550"
- cover
- test tube bed
- motor
- gear with bearing
- gear base
- Motor mount
- rotating rod
- rubber pad( with ninjaflex not pla)
- X shape
Instructions
- Print all the parts mentioned above.
- After printing the gear with bearing, attach the bearings in the space available.(Snap fit should do)
- While printing the gear base , pause it at height of 43 mm , insert the gear with bearing print and resume your print. This way your gear is secured to a place and will not move.
- Attach the shaft of the motor with the motor gear and secure the assembly to the motor mount.
- Take the motor mount , and adjust it on the gear base , such that both the gears are meshing completely. Then fix the motor mount at that point with nuts and bolts , or epoxy.
- Print the rotating rod and fix it with the printed X shape using nut and bolt.
- Fix the assembly of X shape and rod with the test tube bed with nuts and bolt. You may have to dril the exact location with 3 mm drill.
- Print the rubber pad with ninjaflex filament and attach it with the testtube bed using glue or nuts and bolts. Any one would work well.
- Print the case in two parts and attach them together.Glue 2 Erasers at the point where the cover is open leaving 8mm gap between them
- Place a switch in the hole given and solder it to the motor and adapter all in series.
- Attach the printed case with the gear base and fix it with nuts and bolts.
- Pass the rotating rod assembly through the gap between the erasers and fix it on the gear with bearing assembly.
- You are good to go. just turn the switch on and off and see the mixer work.
Notes
- You can print the cover as one print. just modify the design and join both the file to make it sturdy.
Due to time issues i printed it in 2 parts.
