Mitered cutter for panel seal / panel clamps for Clicky-Clack Fridge Door for Voron

The Clicky-Clack Fridge Door Mod for Voron 2.4 and Trident printers is one of the best mods you can do to your Voron printer. The mod uses some rubber strip (aka “panel clamps”) that sits between the extrusion and the acrylic panel. To get a nice looking and optimal seal, one should cut the corners of this strip with a 45 degree (mitered) angle. However, the strip has a somewhat irregular shape, and it's not at all obvious how to orient it to get a proper miter.

That's where the jigs in this model come in. By using these jigs, you will get perfect mitered corners with no gaps (see the second photo). The jig works with the strip from Misumi (HSCPF3H-B) as well as the one that ships in the LDO Clicky-Clack door kits. It may work with others, but I've tested with those two.

There are two cutters, numbered 1 and 2. To cut a strip, first insert one end of the strip into cutter 1. Insert the strip into the side with the arrow on it. Note the orientation - there is only one way for the strip to go in. If it doesn't fit, try the other end of the strip. See the photos if you're still not sure. Insert a utility knife into the slot and cut the strip. I am using a small Olfa utility knife which has a 0.4mm thickness blade, but others should work (see below if your knife blade is too thick). 

Now measure the inside dimension of the extrusion (distance between the two extrusions it connects with). Make a small mark on the apex of the rubber strip - the that when inserted in the jig will appear in the slot at the top (this is what will get pushed up against the extrusion). It might help to use a marker that is designed to mark on black surfaces. 

Now insert the other end of the strip (opposite from the one you just cut) into cutter 2. Again, you insert on the side with the arrow, and it should only go in one way. To make it easier to insert into the second cutter, you might want to first chop the strip off about 1cm beyond the mark. Slide the cutter along the strip until the mark you made is visible and aligned with the path the blade will take when it cuts. (If in doubt, cut it long and experiment, as you just barely have enough of this stuff in the LDO kits). Cut the strip.

If you have the Misumi strip, be aware that the fit will be really tight. So when you go to insert the strip, start by placing just the very end in the extrusion slot, and then slide it down as far as it will go. You won't be able to move it once more than a few centimeters are inserted! But if you get it wrong, you can just remove it and try again. The LDO strip is a much looser fit, so it's easier to adjust.

I printed this in ASA so it should print fine in that, ABS, or any of the easier materials (PLA, PETG, etc.)

Note: If your utility knife is too thick, the CAD sources are included, and there is a parameter to specify the slot width.
