Mini printable lathe V2 + Chuck - OpenSCAD version.
by Daid, published
The size of the guide-rods/axles and screw holes are adjustable in Util.scad
Also some of the main dimensions can be adjusted in the Util.scad
Note that these parts are interexchangeable with the ones from Sublime, unless you change the parameters. If you build this machine from scratch you might want to use thicker guides and a larger guide distance, so the carriage has more stability.
"X_carriage" is flat on top, so you can print it flat on that side, fixes the overhang.
There might be some printing problems with overhang in the bearing_block.
Add step motor mounts so you can make a CNC Lathe.
There is very little clearing between the X carriage and the Z front. Any flex or inaccuracies might cause problems.

Actually, I never got around to print all parts of this thing. When I made this my printer was pretty new to me and I had trouble getting the parts to come out right. Now I know I can print this fine, but I also gained access to 2 real lathes.
Nice! Wonder how much would the non printed parts for one run, and what you could get away with lathing with it, I don't have machine shop access any more, but usually just need to lathe rather small parts :)
The bearings fit! I was waiting to print a few parts before I got that measurement correctly. I should have the X carriage done soon. I didn't print any of the gears yet.
I'm still missing the bolts for the chuck, so I cannot assemble it yet. (The person who was going to order the parts forgot it, and only did so this weekend)

Print everything once, except for:
Upright, which you'll need 3 times.
Bevel_gear, you'll need twice.
Hand_crank, you'll also need twice.
You'll need to print 4 mirrored parts, next to the normal ones: "Z_carriage_left", "Gear_lever", "Cam_lever_part_A" and "Cam_lever_part_B"
For the chuck, print 4x the planet gear. And 4 jaws.
Add 12x 608 bearings.
Add 8M rods for the axles.
Add 6M rods for the guides.
Drill holes larger where I made mistakes ;)
Add a bunch of nuts.
TODO: Add part list for the chuck.
Add a tool holder (see: thingiverse.com/thing:9242 for options)
