This is a fixure for a Dremel/Multitool extension.
I use it to grind the edges of sandwitch structure like herex down to 0mm.
It has two multitool slots:
1) ~10mm chamfer for 1mm material (used for trailing edge)
2) 3-4mm chamfer for 1mm material (all other edges)
Works for 20mm diameter mutitool extension.
Grinder 13mm diameter.
Made for 17.5mm wooden board. Fine adjustment possible by underlay tape.
100% infill required because of vibriation while grinding.
Made for sandwitch structures like balsa, herex, rohacell
