You got nothing to lose by trying! I was skeptical with my prints but that chonk you see above was from one of those syringes I made, and I didnt particularly try to be “as sterile as possible”. Literally just put caps on some foil shiny side down, cut stem from cap and put on foil, then put a jar or cup over and leave for 24 hrs, remove cap and jar and fold the foil in on itself twice, put in a baggy and you’re golden. Bonus points for spraying the table/foil with alc when placing them, and doing it all in a SAB, and cutting the stem with sterile (or alc wiped) scalpel - those will all help with sterility but I didnt do it except just alc spraying down my hands/foil.
Then to make the syringe, I bought some sterile h2o off amazon, but bottled water is probably OK. Open foil in a SAB, scrape the spores into a shot glass or dish, pull up some CCs of sterile water in a syringe and squirt onto the spores, then suck back up - repeat a couple times.
Or if you start getting into agar work, you could just put the spores directly onto agar (by scraping them onto the agar), or pull some up with a sterile cotton swab and rub on the agar
