1"x1"x1.25" Copper Labby Heatsinks

[Laserock]

How many units do you need everyone to order before you can go ahead with the fabrication?

[Mrcrouse]

Part of that really depends on what hole size we're going with in the center. I was originally intending on reaming it to 12mm. If that's the case then, then I need at least 6 units accounted for.

If it's another size that will need a different reamer or an expanding reamer then it'd be closer to 15-20.

Since nobody has asked for the beam height from base, i think there is no real demand for these

People are a bit reluctant to fork out $25 for a heatsink that might not fit perfectly.
You might consider shipping these with an aixyz that has a guaranteed fit.

Change your design to full copper press-fit or at least sandwich-style or SK12 style, no set screws.
