Topic: Magnetic Glass Bed Mounting
Okay I've been kicking this idea around for a while and finally got time to try it out. Whole thing only takes 1/2 hour and the materials are about $10 if you don't already have them. Bed size is 6" front to back, 7.5" left to right.
First buy the glass and some hanger strap, this can be found in the plumbing section of your hardware store, or holding up the rails on your garage door. I used a lock washer on mine, don't know if it's necessary or not.
Drill a couple holes into the wood platform, cut the strap with tin snips longer than necessary. I just marked the first one with a pencil and used needle nose pliers to bend it by hand. You'll want to keep it a bit below the surface of the magnet. Here's the view from below and a profile shot of the brackets.
I just super glued (4) 1/2 dia X .030" thick earth magnets to the underside of the glass. My method was to lay the glass down, stick electrical tape over the spots on the brackets where the magnets needed to be and then flip over and glue.
Here's the finished product, the warning I have is to keep the bracket length inside the glass. My back left bracket was only about .030" from hitting the X motor on my test print. I had to trim it down.
Glass bed is 6" front to back, 7.5" left to right. Bonus area to print on if you wanted. It's not the lock like clips give you, but there shouldn't be pressure on the glass during a normal print as far as I can see, so it's snug enough to print on and not so locked that you distort your brackets putting them on and off. Stronger magnets would work as well if you're worried about it or doing something I can't forsee.
