Front and back pictures of the two slightly different mounting plates. The mount of the switch is different for the X+ and X- plates, due to travel direction of activation.
The plates look nice in either Default Theme, or Dark Theme views in MoI.
The RedLt colored rectangular offsets are to accommodate the pins soldered to the pc board.
The plates mount to 20_40 aluminum extrusions. Activation will be by a 3D printed double wedge, mounted to the moving table...

Thanks for this, Brian! I was tearing my hair out trying to figure out how to do a countersink in a hole. I'm still playing with the MoI demo (I really love this CAD software btw). I hope the developer of MoI (Michael) makes this into a proper feature in the new version as MoI is an excellent alternative to many of the other offerings available. Or perhaps someone would be so kind as to write a script that would do a countersink in a hole.

If you have a bunch to do then make a tool that cuts the hole and countersink in one shot using Boolean > Diff

Hi There

if a hole is too close to a side edge it will often not chamfer as the left block

using a cutting solid will also cut the edge out

cheers

Hi shayno.
Try using the ACIS option for chamfers in V5 - it seems to work just the same as boolean difference.

Martin.

MOI isn't very intuitive for holes when you first start using it, especially if you've moved from a CAD environment

If you want to drill a partial depth hole then you can use extrude/bothsides to your correct depth and boolean it out

ado1, I trained using Solidworks, and tbd, MoI3D comes pretty close in terms of workflow. Sure, there are differences of course, as Solidworks, at least the 2001 version of SW, is a full-on industrial/mechanical CAD experience. But the overall feel of MoI3D is more Solidworks than say, Cheetah3D. I love how MoI3D is very precise when using measurements. Few other 'modelling' CAD's offer that on a budget. It's brilliant that Michael Gibson is still after all these years supporting MoI3D, and because of I'll probably buy a copy as soon as I get paid.

But back to the countersinks, thanks to all about the chamfer. I initially tried that but it didn't work. But now I understand why.
