MySekai "Sketch" Blank Blueprint

Okay, so recently I want to the sketch the chunithm machine my community member has in his mysekai, the thing is I can't sketch, as I'm running out of blueprint, the thing is in the transformation machine it says I need at least 100 surplus blueprint for 1 blank blueprint, in which that would take at least 100 days, and surplus blueprint won't always come, it's from the blueprint you already have, so is there any alternative at all for me to sketch or claim some blank blueprint, i thought by using worldpass it would help, but no, please help, am really FRUSTRATED rn.
