Hi - Great idea! I just printed the pair file on MB Replicator 2 in PLA plastic. The right side printed well (with very tight clearance for the paper) and i could thread the paper through it with some effort. The left side had some melted filament in it and the paper could not be threaded through it. We removed the blockage with a pocket knife and now it works much better. Did anyone else encounter this issue and if so have suggestion for what to do to prevent/remediate the issue?
