Dual commercial NP2.0 metal-cap

[HMC123-puxel]

Hello,
I am building a dual commercial NP2.0 metal-cap Apollo implant and have three short questions:

1. Headstage holder
   Is there any repo file meant for a dual commercial NP2.0 metal-cap build, or would this require custom adaptation?
2. Docking-holder geometry
   With these parameters:
   Inter-probe spacing: 5.2 mm
   Exposed length: 4.5 mm
   the docking holder seems to generate abnormal geometry when exported/printed.
   Is this a known limitation or parameter conflict?
   I attached a screenshot.

3. Skull fit
   For my coordinates, the implant underside is not fully flush with the skull.
   Is a small gap acceptable, or should the underside be modified?

Thanks for all the quick replies!

Hi,

I'll appreciate any feedback:

1. Is the Apollo headstage holder used for a single-probe implant stable enough for a dual-probe configuration with two flex cables connected to one NP2 headstage?

2. Do you know of any skull-anchored NP2 headstage holder/cradle that could increase stability and reduce the overall implant height?

3. How do you route and protect the ground/reference wires in the Apollo mouse implant?

4. If I want the bottom of the Apollo docking module to sit flush with the skull, do you usually fit the implant base angle to the local skull surface, e.g. by estimating the pitch/roll from a skull STL, or is this normally fine-tuned during surgery with adhesive/cement?

any photos, STL/STEP files, or design advice for this would be extremely helpful.

@HMC123-puxel Can you confirm that you tried with this alternate file I linked? I have tried this file with your exact parameters and it works for me... You need to replace the original file with this one to test.

My answers to your other questions are a bit useless I'm afraid:

1. I am not sure if anyone has tried yet... @cbimbo do you know?
2. No, sorry
3. Most people do not use these wires, they use internal referencing and then have a single connector I believe @cbimbo is that your current approach?
4. Normally a combination: adjust the angle in advance to minimise cement.
