Addresses issue raised by timjamesbrennan in back in December 2017 and confirmed by melwell2002 that the Mini has a serious geometry error where the inside corner support gets in the way of the workpiece making it kind of useless for external square clamping. Doesn't work too well as a boomerang either. J-Max claims to have printed many of these that work perfectly, yet the geometry says otherwise.
Addresses issue raised by J-Max that the Mini was never supposed to be used as an external clamp, only internal, and that the geometry fix that permits external use could compromise its strength when using a center-clamp. I haven't printed this one, so can't confirm that claim, but have added an additional model with the embossing fix only (MINI-Internal-NonMarking) so folk can decide which version they want to print.
Addresses issue raised by psykmunky that the embossed lettering interferes with the function of the flat exterior clamping surface, potentially marking the workpiece. This affects the Mini, Midi and Large clamps, all fixed here.
These markings slow the print down, could introduce stresses along the clamping surface that ends up bending the clamp as it cools, and provides a place for debris to collect in - affecting the clamping surface smoothness. None of these are desirable.
No commercial clamps I'm aware of have deep-cut maker markings on the clamping surface. Likely for many…
