How we picked
Each tool had to be free, accept an image or text input, add a proper flange so the cutter stays rigid, and export a printable STL.
Tip: Print flange-side down at 0.2 mm layers. PLA and PETG both work — hand-wash only to keep the blade sharp and the layer lines from harbouring bacteria.
Disclosure: AVDEB is our own tool, so we've placed it first for convenience. Every other pick was judged on the same criteria.
