I found the part that I'd lost and had ordered a replacement for, but it seems I put it in the dryer with my shirts, so the thin bottom part is all bent and the top is broken. It's beyond repair, so I'll have to wait for the replacement part to arrive before I can finish it (´･ω･`)
The other parts are in the finishing stages, so I think it'll be almost complete in a few more sessions.
