Desktop build with zero budget. Critique my design please?

Thanks for the replies all. I've stretched my budget as far as I can. I've changed the z-axis to use 10mm linear shaft bearings on a solid 10mm aluminium plate. The x and y axis will stay with skate bearings but I've changed the 20mm pipe to 16mm round bar. The spindle mount will also be aluminium plate.



If I had the budget i'd go for proper stuff but I have to fork out almost 4k for other stuff right now, so please forgive my frugality. This little project is the only thing keeping me sane.

The electronics will come in time, hopefully when my budget frees up in a few months. At the moment I'd like to get the frame done and sliding.
