Handheld Microtome

Low-cost Handheld Microtome This handheld microtome is specifically designed for shaving extremely thin layers from a specimen for microscopy in pathology and related fields. I have created two distinct versions of this microtome, each with its own unique feature set. One version includes a space to accommodate an M11 washer, while the other does not. The plug is an optional design element that can be printed if desired, offering additional surface area for pressing down on the specimen. All necessary materials required for assembly will be listed in the post-printing section. For optimal results, it is recommended to print the top part with the wide base facing downwards, ensuring a flat surface for the razor. This setup ensures accurate and precise cuts. Post-Printing Materials: 1 - M11 washer (24.0 mm outer diameter) 1 - M10-32x40 threaded rod 1 - M10-32 nut 60mm of 1/2 inch OD aluminum tube (.444" inner diameter) 25mm of 3/8 inch OD aluminum rod (.375" OD) Super glue Sandpaper Instructions: Print all required parts Finish printing and sand any rough surfaces if necessary Cut the aluminum tube and rod to precise lengths Assemble the nut and bolt using super glue or press-fitting Attach the M11 washer to the aluminum tube using super glue or press-fitting Prepare the specimen according to standard procedures Adjust the height of the specimen relative to the cutting surface to achieve extremely thin layers.
