Spoilboard Stop for Homag Centateq N-300

Had an issue with certain materials pushing the spoilboard backwards when automatically loading on my Homag Centateq N-300. These brackets mount to where the pop-up pins would be (Field 3 and 8 I think? Whatever the two left fields are). Obviously this doesnt work if you have the ability to run in all 4 fields. As for infill, you should probably print this thing with decent infill, seeing as the spoilboard pushes up against this thing often. I printed these out of PETG but I'm sure ABS would work and probably even PLA if it was printed with high enough infill.
