I have an arcade stick which has an acrylic top plate backed by 10mm+ MDF underneath the artwork. I am about to replace the acrylic plate with a new one, but I realized that the Blast City template is a little askew, so when I laser cut a new plate one it won’t fit exactly on top of the MDF anymore.
So my thought is to cut the new acrylic plate and then fix the button clearance by cutting out about a 5mm offset around all the right hand buttons so that the acrylic has nothing under it where the buttons are sitting. Is this a bad idea when considering durability? Is 3mm acrylic strong enough to hold without flexing or am I likely to get cracking between the buttons and so on?
Another option would be to cut out the clearance in the MDF and then use a 1mm steel/aluminium plate and a 2mm acrylic plate on top of that to make it stronger.
