ETA TPU brushes

Designed for myself, but it could help others. Designed with 3d printing in mind. The brushes are printed with tpu, the core or the insert is printed with pla or petg. There is only one postprocess thing you have to do, warm the place where is the small slot on the brushes, warm it with little bit of fire or soldering iron, and bend them down a bit, it is needed for proper work, there needs to be few degrees bend down to clear under the vacuum. Send me a message if you need some file edit, i will edit it. Vacuum model ETA Falco Smart 2515 90000.
