After many months of testing I present the magnetic action exacto knife, great little tool for arts and crafts, opening boxes and also fun as a fidget toy (use responsible ;) )
You will need three 5x2mm magnets which will need to be glued into their dedicated holes, make sure you get the polarities correct when glueing them in so the bladeholder magnet sticks to both handle side magnets. Bladeholder and clip should be printed on a smooth surface/pei plate to ensure a smooth gliding action in the handle. Handle should be printed vertically/standing up with a large brim.
The model is compatible with original X-ACTO nr11. blades and generic exacto blades. The generic blades have a 6x2mm slot in the base of the blade. The blade clip locks the blade into the bladeholder and will need some force to be fully pushed down, it is a tight fit which ensures the blade has a solid mounting point. When changing a blade the clip can break due to the tight fit so it is avised to print a few spare clips if you plan on changing often.
