This is an open-source 3D printed microscope. Read more about it here : https://openflexure.org/
The following parts can be buy from suppliers that are in the Aix-Marseille University public market list.
- 3x M3x25mm hexagon head screws, stainless steel
- 3x M3 brass nut
- 1x M3 steel nut (using brass is also fine)
- No need, used brass nut from above link
- 8x M3 stainless steel washer
- 3-14x M3x8mm cap head screw (some are optional, for sample clips and sample riser, but you will need at least three)
- 2-4x M2x6mm cap head screws
- 6x M4x6mm button head screws (optional, for motors)
- 3x Viton O-ring, 30x2mm (NB: get some spares!)
- 5mm White LED
- 60 Ohm resistor
- Stranded wire
- 2-way JST header connector (so long as you have some way of lighting up the LED, it doesn't much matter)
- Raspbery Pi camera module (v2, though v1 works too)
- Raspberry Pi (with associated power supply, keyboard, monitor, etc.)
- 3x 28BYJ-48 micro stepper motors (optional)
- Motor driver board for the above (optional)
- 13mm diameter, 5mm focal length plastic condenser lens (optional, strongly recommended for high resolution optics)
- 12.7mm diameter, 50mm focal length achromatic lens (for high resolution optics only)
- RMS threaded, finite-conjugates microscope objective (for high resolution optics only)
- Get it from a microscopy platform
Here are the parts needed to build the PSU layer to power both RPi and stepper motors:
