Ordering and assemble the drive yourself
The .step files are optimized for stainless steel 316L, 20 micrometer resolution and aluminum AlSi10Mg, high resolution using Proto Labs (https://www.protolabs.com/). Download step files from our GitHub repository.
In order to receive high quality prints from ProtoLabs, please follow these instructions:
- Add the following note to drive_v09: “Use orientation as in quote 9301-742”
- Add the following note to arm_v09_aluminum: “Use orientation as in quote 2379-080”
For other printers, materials or printing companies, modifications may be necessary.
Purchasing fully assembled microdrives
To purchase fully assembled drives, please contact 3Dneuro (our partner in production).
Assembly instructions
See video below. Detailed assembly instructions are available for the metal microdrive and for the implantation tool.
The assembly video is also available on youtube. Neuropixels probe attachment (or any other silicon probe) are available here.
