Garage Door Seal Trimmer

thingiverse

The garage doors I have are old enough that the current weather seals for the bottom don't fit anymore. The only seals I've found for 'T' channels are 5/16" ones. My garage door requires a 1/4". That's why I built this trimmer to remove 1/16" (1/32" from each side).\n After it is printed, clean the insides of the 'T' channel so the rubber seal can pass through without resistance.\nI need two single-edge razor blades for it to work. But you'll have to modify them first. Use a rotary tool to cut away the center part of the razor blade stiffener, leaving only the razor blade itself visible in the seal path. If not, the seal won't pass through easily due to the thicker stiffener getting in the way. Leave some stiffener on the ends so they fit snugly into the slots.\nTo use it correctly, push the seal into the trimmer towards the sharp side of the razor blades. Once the seal starts exiting out the back, begin pulling it and the cuttings. Although it's not perfectly equal on both sides of the 'T', it will be 1/4" long and should slide into the channel on the bottom of the door.\nBe extremely careful, as the razor blades are very sharp, and differences in 3D printers might cause them to slide out while using the trimmer.
