Inexpensive 3D printed parts to easily attach to basic stereotaxic equipment. Several designs are shared and can hold MiniScope microscopes, fiber optic cannulas, neural electric array probes, both optics and electrodes, and just a general wire holder.
This is a collection of parts that easily attach to stereotaxic equipment. With one M3 10 mm 6-32 screw and one 6-32 nut (no glue even) the parts can attach to the basic 6 mm diameter stereotaxic rod. Another set of 6-32 screw and nut allows for the parts to clamp onto what is to be implanted. Currently, there are revisions that allow for
- optic cannulas (fiber optics for optogenetics, including a 1.25 mm or 2.5 mm ferrules or associated sleeves)
- electrode arrays (special attention to Neuronexus probes)
- both optic cannulas and electrode arrays (record while you stimulate!)
- a variety of wire sizes (meant to hold the wires out of the way)
- a drill
- the microscope portion of the UCLA MiniScope
- RIVETSRemix
A variety of horizontal holes on top allow wires and fiber optic patch cords to be held. No special tools are required for assembly. Release of the component post implantation only requires one hand (phillips screwdriver).
I’m an engineer with no marketing experience. Please pardon the name (Neuroprobeamajiger).
** Update for May, 2019: Printing in SLA yields better results. I have also included a zero force optic holder. Some researchers didn’t like how the previous version required a screwdriver to release the optic cannula, so this design gets rid of that. Simply get some Micro Toothless Alligator clips, bend them a bit with pliers, then you can simply release the cannula with ‘zero force’.

Printing profile
Parts have been successfully printed with either PLA or nGen (preferred) with standard Cura settings (normal or high detail), 20% infill. No supports are required. The Neuroprobeamajiger that clamps both the optic and electrode has supports designed in. They easily break off after printing and ensure sufficient support.
ONE Core acknowledgement
Please acknowledge the ONE Core facility in your publications. An appropriate wording would be:
“The Optogenetics and Neural Engineering (ONE) Core at the University of Colorado School of Medicine provided engineering support for this research. The ONE Core is part of the NeuroTechnology Center, funded in part by the School of Medicine and by the National Institute of Neurological Disorders and Stroke of the National Institutes of Health under award number P30NS048154.”
