This morning I got the extra print completed. I'm using the #elegoo #mars3. For material I'm using #Resione #w90b. It's flexible so I can add flexures for mirror steering which is what those squared cut outs are for. The start angles I used are for parallel chief rays. That definitely doesn't work. However on my second fail I learned that you want to start parallel and add a flexible component. Did I mention that you don't save money by doing this? I'm probably at $18 worth. $13 : 60x2" mirrors
