Gridfinity Holder for Zephyr Microstop

This model is kind of a follow-on to the Gridfinity tray I recently posted for the countersink kit from Aircraft Tool Supply.  I had this other Microstop that didn't fit the recess of that model, which I wanted to put in the same drawer with the rest of my aircraft sheet metal drilling stuff.  So I made this model to fit in 1x3 squares, and added recesses for a couple of extra countersinks to use some of the space around the end.  The recess for the microstop is designed to fit no matter what length the cage is adjusted to.

The ZT330 microstop that I made this for was included with a bunch of other random drilling accessories that came with a Sioux air drill I bought off Ebay 20+ years ago.  Remarkably, it appears this microstop is still available new and in several different versions.  The one I have with the wide base (which is removable) appears to be the ZT330SP.  From what I can see, some of the other versions should also fit in this holder, but YMMV.  If you have a different model of microstop that you find fits it, please post a make with comment describing what you have.

Like my other Gridfinity models, the base is altered to accept 6x3 magnets as a press fit, with the upper surface of the magnet holes modified to make the slicer bridge across correctly for a clean result.  Due to the size of this model, I have included sacrificial “mouse ears” in the CAD to give the ends more surface area to help prevent them warping off the bed.  These will need to be removed after printing.

The unit pictured was printed out of Overture PLA on my bear upgraded Mk3S+, using a 0.6mm nozzle, at 0.3mm layer height.
