Portable Centrifuge
This was mainly developed for manual hand powered, where the idea is to have a string attached to the inner part, and pull to rotate. The spinner is made for 6 pieces microcentrifuge tubes, 1.5 ml/2 ml. With the correct pulling force, the manual spinning create self-winding the string.
The parts are made so it is fairly easy to print, with no support needed. I did also included som disassemble files, so it can be used in different settings, those are located in the misc folder.
V1 parts have a print file for complete in one print on a Prusa MK4. Brim is added to the Top and Bottom taps. V2 parts does need some support.
Parts V2:
- 3D printet parts:
- Handle
- InnerPart_Plain Or InnerPart_Drill
- BottomBase
- TopBase
- Spinner
- BottomRotate
- LidBottom
- LidTop.
- 2 x Bearings (I used ILQ 9 Pro) standard size 7x22x9mm. These could also work: bearings 608 Ball Bearing
- M4 screws, preferable flat screw head. two screws: ≤15 mm.
- String/thread
- Optional rubber bands to keep the top and bottom base firm, while using the centrifuge.
- 16xMagnets 5x2mm, they should snap ind and maintain the position, if they get loose over time then superGlue will help.
- M3 screw for InnerPart_Drill, preferable round screw head: ≤45 mm.
Features:
There are made a drill bit, so it can be used for with a drill to centrifuge, the speed should be set to low. There is four slots on both bases, this is for rubber bands, the lid is made both with and without knobs. The konb lid is to easier detach the lid from the top base. The spinner as assembled with a screw to the top tap, it is possible to design different spinners and use. For fast printing the fullInner part can be used, but for easier print it should be better to find the different parts in misc folder for the inner tube.
