I will probably get most off the parts from aliexpress and i have tried to get all the demensions from there but there drawings are very small and hard to read ,does any body have any links were i could get the measurements

You can find Cad models of parts like BK/BF bearings. They are standard dimensions across manufactures with only slight cosmetics differences so provided you get right model they will be ok. If can't find Cad modles then just search for BK12 or BF12 which is the size for 16mm ballscrews and you'll get loads of dimension charts.
Same with steppers Nema23 is standard size for mounting only the length changes with model type.

Similair with ballscrews and ballnut. The size and dimensions of the ballnut are common standard dependant on style. You'll use flanged type so again you'll easily find dimensions for 16mm ballnut with only slight differences in length.
Ballscrew machining is again standard dependant on bearing type with only the very end dimension changing according to your spec. This is what Clive is referring to when says F dimensions. Same here type RM1610 end machining and you'll get loads of dimension drawings which will suit BK12 bearings.

Also when designing the brackets for the Motor take into account the centre distance between screw and motor along with pulley size for belt length and make sure you can buy belt the right length to give adjustment you need. Very easy to find there isn't belt size that covers for Centre distance.
These are the little hidden details which get missed and bite you in the arse after all parts are machined.

The one other area on this design which is close is the drop down bracket for ballscrew. Gets for tight when approaching the end bearings so pay close attention here checking for clashing.
