My #3DPrinted #MorseCode key design is coming along.

The cover/handle works really well, I think. I printed it just long enough to be comfortable in my hand. Someone else might want it shorter or longer.

Meanwhile, I've also designed a belt mount. The belt goes through slots in a base that goes under the key, and it goes over the key to make it a solid fit. I could have done one where the belt goes underneath, but this seems like it would be more solid. Then the key slides into a block that swivels, and a few more thumb nuts lock it into any location you like within 40° left or right of center.

This is extremely parametric. The height of the block, the allowed degrees of swing, how thick and wide the belt are, how wide the whole thing is; most of the dimensions are derived from parameters.

This is the second revision of the base and swivel. The first version didn't swivel far enough, the key wasn't raise up far enough above my leg, and the whole thing was too wide. If the key isn't high enough, I inadvertently TX from my pants leg fabric brushing the key. This is because I have the key set to maybe 0.5mm travel to each side; it's quite sensitive. On this iteration, it's slightly too narrow; I can only fit a thin belt through it because the thumb nuts that lock the swivel in place interfere. The next version will be just a little wider.

I think I'm ready for some beta testers! Folks who don't mind running FreeCAD to adjust parameters and print multiple copies to adjust for the filament they are using could help make this good for others. Any #HamRadio #AmateurRadio CW enthusiasts also enjoy 3d printing and want to try this?

Robot Acceptance Factor is acceptable. I'll find out later whether it knocks the ramp away when cleaning the hallway.

I measured the door frame on the right and designed the ramp to fit around it. But of course the frame isn't symmetric, and the left end doesn't fit. That end is going to have an unpleasant encounter with Mr. Dremel...

I am printing a ramp to help our robot vacuum get over the threshold into the laundry room. Three of four sections are printed, plus a couple of test prints in black. I'm trying to use layer lines as a design element. N.B., the herringbones are not parallel -- they're straight at the edges and diagonal in the middle. I got the effect by lofting from a flat edge to a shallow sawtooth and back.

For the stocking themselves I finally made a sort of "name tag" so that people could figure out which stocking goes to who. I semi-randomly pick stockings to fill based on how much stuff needs to go into them, so I've never sewn names onto them. Instead I made custom #3DPrinted pins of things that certain people are very into. For my mom an alligator, Snoopy for my dad, "caffeine" for my sister, and of course the #RetroBattlestations logo for me.
