The Marauder’s lights were dimmed to emulate night. The only illumination in the ship came from the floor lights, control panel and the smear of stars as the ship zipped through the hyperlane.
Echo used the flattened and stretched starlight to see as he worked Tech’s mini air compressor around the head of his scomp. Small bits of metal and wire fell into the cloth across his lap; no wonder the thing hadn’t been turning smoothly since before he’d driven it into the head of that battle droid. He tucked the compressor away and tossed the debris into the scrap bag to be dealt with later.
He ran his left forefinger around the edge of the scomp and, with only a thought, made it spin. It turned smooth, slowed to a stop when he willed it. And for a moment he found himself marveling at how quickly you could get used to something so new, so strange.
Before his surgery on Anaxes, Kix had given him a choice to have the scomp removed. With the caveat that he had nothing, at the moment, to replace it with and it might be 30 rotations or more before they could make that happen. If they could.
Echo had chosen to keep it. Even if they’d had a mechno hand ready for him, he thought he might have chosen to keep it. It was...useful. Though he could admit—thinking of the empty sketchbook he’d found in the Tipoca City library, now tucked carefully away in his pack—there were some things he missed having a right hand for.
With a sigh, he spun the scomp once more, making sure it turned solidly. He’d need to remember to oil it when he got a chance; he’d left his bottle on Kamino, still not quite used to some of his new needs. In the back of his mind, he could hear Fives making a joke about him forgetting the lube.

I keep revisiting this bit, mentally. And after the most recent episode of TBB, I think I'm definitely keeping an idea I had for the second, larger part of this series.
Also, yes, I headcanon that Echo sketches. If you were able to see the reg manuals on his old datapad, in addition to underlined important bits and notes in the margins, there would be doodles.
Though I'm sure that's not the only thing Echo misses having a right hand for. Good thing the clones are pretty ambidextrous. (I'll show myself out.)
