This is what happened to me when I purchased a Cricut machine (not for scrapbooking) and the co-ordinating markers and deep cut housing. I knew this would continue unless I got more organized but didn't tuck them all away in another plastic tote that I couldn't be bothered to dig through when inspiration hit.
I didn't realize that I chose the opaque code and this is how I ended up looking for something to use it on. Really any polycarbonate will work fine if you have enough surface area for the quantity of markers you have.
Next I gathered a square, a acrylic sheet cutting blade (not shown), my ever trusty Xacto blade and a set of circle templates. I used the template because it's easier to eyeball the placement of the second set of circles AND I could actually poke the marker through it to test fit.
Can't do that with a compass.
On one piece I traced a circle big enough for the applicable items to slide through. On the second I drew circles just shy of that measurement. If you have a template, you don't even need to measure - just pop the marker through until it just 'sits' nicely on the bottom hole.
Another benefit of the templates is that when you place the 'bottom' piece on the top one, you can see through and just need to layer the template over both to accurately line everything up.
I rough-cut the holes with a drill and then finished hollowing out with an Xacto.
Note: be very cautious with the sharp tools - they are sharp.
See proof below on my left thumb...
On a brighter note, I was wearing my safety goggles and watched my pressure. Once the holes were carved, I used my dremel with 2 polishing bits to smooth out the edges.
Then I decided to try out my new heat gun and mold the top piece into a self-mounting plate.
I should have tested the idea out on scrap first because I heated one corner a bit too much and it curled rather than slumped. I ended up molding two brackets out the same material after one more practice run. I simply cut the curled portion off and used the leftovers to make the no-longer one-piece mounting bracket.
Did I mention that I love epoxy?
I was less than impressed with the fact that the package failed to mention that the hardener was a puss yellow, however, I digress.
I took a break from all this hard work to visit a new local clearance warehouse. I picked up a couple of fabulous adhesives and some cutting oil. Almost like the candy store. (hmm, maybe I need to get out just a little bit more?)
Now all I have to do is hook up that Cricut.
