This is a prefilter for the Xtool f1 Ultra.
You need 8x 10x2 Magnets (10x3 will fit too) and a piece of exhaust hood filter or similar.
Fit the magnets in he holes on the base and the top then push the base into position.
Cut the filter with the cutting help and use the prefilter_top_insert for fixation. If you use a thicker filter, scale the height of “prefilter_top_insert”.
