Awsome work on the sump and other acrylic! Really classy and makes me wish I had a laser! The etching possibility is what I’m missing. You can do a lot with traditional woodworking tools but clean work like that is hard to achieve without a laser.
Did you have any problems with getting clean cuts on the 1/2” material? I saw that you made multiple passes. I’ve just seen that process go badly with the acrylic heating up to much and not yielding a clean 90deg edge.
Also, what brand laser do you have? I think you mentioned but I forgot. I’m down the road from Epilog. Maybe I need to stop in their facility to see if they have any scratch and dent models or prototypes that didn’t make it to market.
