Comments on my first attempt at a design (if you would)

Double the vertical size of your Z axis carriage, at least.

Thanks, when i first modelled it i had the wrong linear rail blocks and the height of the z carriage came out at 175mm, when i actually put it together ang butted the blocks up it turned out it was 100, so I re-modelled it to suit.

It did strike me that is looked wrong then but I've already made the dam thing.

I think that will be the first job of the mill, to make a new Z carriage mounting plate. Ill change it on the model to make sure nothing else will clash later on
