by the way, what keyboard are those key caps from? the alphanumerics, shift, break (stop), and enter - they're super pretty. I searched around, but I couldn't find much.
Assuming those are abs, you can repair the dent in the shift by using abs welding compound. It temporarily turns plastic into slightly malleable gel. So you could shave off a bit of the plastic from the underside of one of the caps, mix it with the welding compound, then put some welding compound on the ding, and then put the plastic filler on that. it'll heal up and look like one part. once it's one part, let it get firm, then put on some more welding compound, and form the ding to be flat again using something smooth like glass. you might have to sand a little. after sanding, give it a quick wipe with the welding compound again to give it a nicer finish. for this amount of work you should use like half a drop. not sure where you're located, i bought
The Bloq Plastic Weld and had great luck repairing and reforming tiny plastic pieces. Like those tiny screw shafts that hold together two parts of a plastic housing (in my shaver), or those tiny tiny teeth that snap around the other part of the shell. Also repaired the clamp on the battery compartment cover for my old sony tv remote this way. it hadn't broken off, but when i bought it it was bent away so that it didn't actually latch shut. a little of this compound made the latch soft and i was able to reform it.
