Thanks for information. How well may enclosure’s own heatsinking perform, e.g those enclosures in amazon black friday offer, ONRICO brand certain number of models, for US 100 up to 112USD. Or Acasis in similar price range.

I would try with slick new scraper/spreader/spatula for wall works width 2 inch or so then by positioning it on rotor against residue at as small angle as possible.
