    World's Easiest Silicone Mold.

    Maybe you could drill or punch a series of holes along the edge of the dust and and allow the silicone to ooze through them creating a thin layer underneath the edge of the pan. Of course you could use duck tape over and under the existing lip, creating a thin extension of the lip.

    How to Make Your Own Sugru Substitute

    You could try a spatula or the like (or your fingers) covered with a thin layer of vaseline. Rubbing alcohol followed by a little detergent is supposed to remove any traces of vaseline. YMMV; I have not tried this.

    You could try imbedding neodymium magnets and letting the goo/gru cure completely. Assuming your locker is metal you would have the ability to remove (or just move) whatever you make at will. Just remember to leave a thin layer under the magnets to keep them in place.

    You can buy reusable nozzles that screw onto the caulk tube tips. The nozzles have a series of screw-on caps which give you a choice of bead sizes. Make sure the nozzle is full of silicone before you seal it. That way the plug which inevitably cures in place will be in the nozzle where it can be easily removed rather than being back inside the original tip.

  • HOW TO MAKE a MODED GLUE GUN / Tutorial / DIY

    From a Google search, it looks like you need a 5/16-32 tap. You can make one yourself from a bolt:https://www.instructables.com/id/Make-a-tap-from-a-bolt/

    If you have a glue gun with a removable tip, it might be easier to remove before molding.

    A variation of this idea is to use a spring, like you see in soldering iron holders, with a piece of ceramic tile to catch the drips.

    Another cheap n' easy solution is to cut a piece of PVC of appropriate diameter to a stable base. This also works well with drills.

    3D Pantograph

    After a quick Google search I quickly learned that moving the pen along its arm creates distortion in the copy. The tracer, pen, and fixed point have to be in a straight line. The only way to change the ratio is to change the ratio of the distances between the pivot points. Here's an article explaining how the pantograph works and how to design for the desired enlargement or reduction. Often the pantograph arms have a series of holes for the pivot points, allowing you to change the ratio at will.http://designandtech.ca/pdfs/solutions/5271.pdf

    I just got a rotary tool kit including a flexible shaft attachment and this seems to be a great addition. I would think you could make the ratio adjustable by using a series of holes or a groove lengthwise on the drawing leg and moving the stylus towards or away from the dremel. This would allow you to make the engraving smaller or larger to fit the size of the workpiece. Of course, now that I've opened my big mouth I'll have to build a proof-of-concept.
