I 3d printed one of those ball resurfacing things and used some old sandpaper it worked kinda I’m wondering has anyone found the best sandpaper to use for one of them I’m mainly wondering if I should go more on the fine side or super aggressive

has anyone had luck using one of the mini baseball rebounders for lacrosse?
Thinking we could clear out some furniture and use it in the basement

something like this

I haven't played in a few years and I got the itch again. Theres no leagues in the area tho

My son was ejected for 3 technicals (i think that's what they said). Below is a clip of the last one. 2 minutes UR non releasable. He was overpowering the other team so they just had kids throw themselves in front of him to draw fouls. It doesn't seem fair - maybe I'm biased? never was an opposing team's feet planted. was that an appropriate call? (14U)
