For those who may not have noticed the discussion on this matter in another thread, which didn't start out on the subject, it was suggested that I should start a specific appropriately titled thread.
I designed an open comb base plate to be used with any Gillette Tech Cap, and had it 3D printed using SLS (selective laser sintering) in PA (nylon). I built it to try and replicate the Gillette Old Type geometry I had measured, which has approximately 0.07mm blade exposure, with the blade clamped hard between the cap and the base plate. A Gillette Old Type Tech Hybrid was the intention.
The 3D printed component came out very slightly undersized to the design, just over 0.1mm less in width, which doesn't seem like a lot, but it was enough to turn the combination into a dialed up one notch Gillette Old Type experience.
Given that tolerances like this will be experienced when printing, I decided to make three versions in order to account for it. Mild, Medium, and Aggressive. Printing for each one should be less than $10, and so long as you use the same printer and material, you could print the Medium, see if it's what you want, and then move one direction or the other for the next print if you need to. By design the Mild has zero blade exposure, the Medium 0.035mm, and the Aggressive 0.07mm. If the typical printing tolerances only swing down, then the blade exposures for each might move up about by 0.03mm. Hard to say, but you've got three to choose from at least, and room to move.
The attached ZIP file contains a 3D printer STL file for each of the designs.
