Very Cool idea, that will make the intface even more accurate! I made a change to mine also in time my centers raised so i made the four outer center scews longer and fixed them to the plastic also. this really makes it solid. You might want to do it also. Scott
Finally went ahead and made one of these. I glued in ball bearings instead of screws to hold the plate against the magnets. So far, it's working great.
I do agree, i will put a termal couple on it today why i am making some parts so we can see the actual temperature. From the touch i don fel much heat at all. I guesing 50 to 60 degreess C max. I will post what if find today. Scott

Instructions
2nd Cut holes as show in picturees to mount the magents and glue them flush to the wood surface. I used JB Weld, that stuff glues very well!
3rd Print the Leveler parts and put it togethere. You do need to grove out for the flat head screws so they are flus with the plastic (see picture). They are 3mm Hex Flat about 4mm to 5mm long. See thingiverse.com/thing:9094 for the leveler parts.
4th Dont forget to sand the wood and the corners so the platform sitts on it very easy but not lose!!!!
5th It not mandatory but i would also print and install the new power connector i posted. This connetor will handle reppeated removales. thingiverse.com/thing:9090

Cool!
I just added a link to this thing from my quick-release for the Automated Build Platform
Could you post the source files?
Just posted them for you. Note the rev A has support built in and this is the way i printed them. The Rev B does not have support if you wont ReG to do it for you. Scott
Those aren't neodymium magnets, are they? If so, how long have you been using this for? Neodymium has very low heat tolerances; if I recall, many types lose their magnetism at around the same temperature the HBP usually operates at.
I may be wrong, or these may have a different composition, though.
Can you (or somebody else) tell me if neodymium has a heat tolerance of 150 degrees Celsius?
Thanks!
Just a Note remember there is very little thermal path from the platform to the wood. Actually there really is no path execept what getts dispated through the plastic from the fou leveling scews and it is very little. Scott
Not to weary they will not see much heat at all. Also if they do it will be disipated into the wood very nicly. I have mine running right now and my plarform is 110 and the magnet s are cool to the touch. Scott
