Share your prints
yes...why are those so crazy expensive???
nice job.


p.s. I would post mine, and some other prints...but just keep getting an error when trying to do so. even just a small 100kb .jpg
tried Eds tutorial...cut and paste screen grabs...etc.

Hey Hey...Using my laptop seems to make this work...so here we go. Smiley-dancenana
Been working on a CNC lathe tool turret design. Decided to print a prototype. didnt think it would work out as well as it is.
Even the printed threads on the end of the spindle fit perfect!!
Just using a stock Ender 3 Pro, and some no name PLA from a sample kit that came with it years ago.
I did print the spindle in 4 parts, and ran a bolt thru the center. this way I can redesign and reprint individual parts of the spindle if need be. Plus I can print each part flat with no supports.
The one that inspired this was an Emco Compact 5 lathe turret, and they use a DC motor driving a worm gear setup. That gear setup is $200 from McMaster, so I'll use a spare stepper and cheap driver I have in stock. Will probably Arduino controlled.

I'm more interesting in knowing how much life you will get out of those 3D printed inserts! I'd seriously like to cut down my costs there!

Rotfl That would be cool eh?? Star Trek replicator..."computer...tool...lathe...carbide"
those are actually real tools Blush  well, as real as cheap Harbor Freight "carbide" can be.

few new bits for the cnc lathe tool turret prototype.
I printed the case in two halves so I could control the top surface better without having supports mess up the surface.
The action on this is really crisp, and better than I imagined for a printed assembly.

Before and after storage of mill clamping components. I still need to make some threaded rods to go into the brass inserts to hold the flat washers and nuts.

Please post the files.I really need something like this as the metal ones really don't work all that well.

You'll likely need to change the dimensions for the t-nuts and possibly the threaded studs since my mill uses 3/8" threaded studs. For the t-nuts I bought some from McMaster to get started. I have some I'm going to make that fit my t-slot better so that's what the second row that is currently unused will be for. I'm assuming your mill probably uses 1/2" or 5/8" studs in which case the strap clamps will be wider than mine. I've attached both the FreeCAD and stl files just in case.
If you want to send me the dimensions of your hardware I can make the changes for you and generate new stl files.

more test parts. this time for a small mill CNC conversion project.
I always get stuck in "analysis paralysis" while staring at stuff in my 3D CAD. So i've started printing prototypes before machining metal. specifically to make sure holes are in the right locations etc. easy enough to start a print in the afternoon or evening and have finished parts in the morning. what a time to be alive, eh?? I cant imagine what it will be like in 10 or 20 years.
