"CMT and a few other companies make these (still for use with extraction, but to help send it the right way). Was just ordering one this week. Pricey, but it means we can do 18mm melamine in a single pass and leave the bed clean afterwards. Maybe a bit different in that they replace the collet nut but same principle. I think the 3d printed version is a nice idea for its target market https://www.voswebshop.nl/webshop/992.101.ER32.html"

"Muji have had a similar product for some years, which I think is a bit kinder on the eyes https://www.muji.com/sg/products/cmdty/detail/4549337308121"
