Don't try this on the Dremel ideabuilder 3D20 - the platform is mounted too soft and will "give" under the load of each of my 6 different indicators. What a pity, but this soft mount did save quite a lot of prints too...
So I stick with the paper method....

I "remixed" your design, actually made it from scratch in OnShape. It foregoes the use of magnets, uses a wider base and has a bit tighter tolerances. It alleviates some of the design concerns I had: side-to-side rotational play, indicator shaft play, use of magnets, M4 screw a bit loose, rotary dial face skews indicator.
Not saying it does anything better, just that it's a bit faster and more precise to use, although it's basically the same design.

I like what you have done and I can see how the improvements work, nice job.

The others didn't work because they are all designed wrong and yours will not work for them as it is wrong too :)
You guys have obviously never been in a shop or metrology departement..

When I said “the others didn’t work” what I really meant was they didn’t fit my cloned machine. I think it’s wrong to assume the designers of these Jigs are not familiar with industry, although I do appreciate the futility of trying to perfect a level heated bed. Most beds are warped and these dials enable us to visualise areas of serious deviation they also speed up the levelling process compared to using “a piece of paper” as a feeler gauge. They really do work, to cut down hours of fiddling. The aim isn’t to achieve a perfect level surface it’s to speed up a horrible job :(

I use a dial caliper and I comented on the wrong way you mount it as the others do too. There is ONE guy here who was close to something OK and I told him how to make it correct. Don't remember who and don't want to repeat as it is becoming boring. So do a search. Anyway, in less than a week an other will reinvent a similar incorrect stuff.

So who is the other guy? Or other design? What is wrong? What is the correct way? Without any mention of those it's not really constructive criticism, just bitching.
