TM5 cutter temporary fix

On my Thermomix TM5 the softer part of the gear coupling to the motor eroded through heavy use, so the cutter didn't cut and mix all the way to the floor of the mixing bowl leading to non homogenous results. Ordering a replacement was not possibly due to being out of stock due to corona. so I printed 5 nylon washers each 1mm high and cut them in one place with the Stanley knife so I could put them on the axle. I put some vegetable oil on them for lubrication. it works for now and hopefully until the replacement part arrives...
