I’ve also been looking at potential parts to use instead of printing them on a 3d printer.
Being able to construct this using just a CNC mill and off-the-shelf items would be fantastic.
[li]The centre assembly could have the bearings replaced with SC25UU 25mm linear bearings (unfortunately expensive).[/li]
[li]An aluminium version of the stepper mount on the Z Assembly can be purchased pre-made on amazon. I’m not too sure about the tube brackets on the z assembly[/li]
[li]The side assembly could use spacers and more linear bearings, a couple of those bits would be tricky to find purchasable replacements for, though.[/li]
