The front wheel on my Samsung Jet bot combo AI cracked (all plastic). Samsung wants 70 euros(!) for a new one - so I built my own with parts from Biltema (a Swedish low-cost construction- and goods store) for just under 30 SEK (about 3 euros). Works like a charm.
Is the bandaid on your finger related?
Could have been (no redneck engineering without a little blood), but that was a cooking injury. A global knife that basically cut my fingertip in two. Good thing I have quite good healing flesh.
