For those of you who use purchased altimeter sleds: Do you have a preference for having pre-drilled holes for altimeters, or would you rater the sled be blank?

There was a preference for pre-drilled holes years ago when I first released my sleds, and I want to make sure that is still the case.

Any other feedback is always welcome.

Blank. I have 3 different brands and 4 different models within those brands, all with different mounting holes patterns. I try to marry 1 board to a sled but sometimes I do move between them.

Pre-drilled for me.

If I have to drill into a blank sled I won’t have the “nub” that adds additional space for threading in a tri-lobe screw. This means additional bits and bobs (nuts, spacers, etc.) are required to mount the altimeter.

Pre drilled. Though, with all the electronics options, the board looks like Swiss cheese!

Pre-drilled, as in pre-molded in bosses and holes for 3D printing. Works perfectly. Makes for instant installation and no possibility of a ruined mounting.

What about using thin pilot holes at the locations? I don't have any preference personally as I print my own.
