3D Printer Recent Production

The main things I've been printing are add-on for my Anet A8. I ran most of these over the weekend. Because of the length of time on each one, I could start a run then go inside and chill out for a few hours. OctoPrint allowed me to keep an eye on the printer from my recliner.

Frame stabilization parts that took a combined 15 hours to print.


Y-axis belt tension adjuster.


X-axis and Y-axis belt mounts. The factory options just aren't right.


Corner supports for the glass I use on my heat bed. These will allow the glass to sit in place without binder clips


Thumbwheels for bed leveling. One above the H-frame and one below. An M3 nut will press into each one. I'll drill out the threaded hole in the H-frame to allow the bolt to slip through.


Filament reel hubs and end bushings. Bearings press into each end of the bolt and fit onto the threaded rod that came with the printer.


I've saved these until today so I only have to take my printer down one time to make the changes.

Nice. Did you do a tensioner for the X axis? I'd recommend it also, the one on my printer page that moves the idler pulley outside the frame.

Edit, that Y Belt attachment looks similar to the one I did, but the hole patterns weren't correct. I just ended up putting the originals back on and using them with the tensioner and they've worked.

I haven't done a tensioner for the X axis yet. I've been looking at them and kinda settled on the one you used. It'll be simple enough to add it since I don't have to disassemble the printer to make that modification.

The Y tensioner I printed fit everywhere - had to sand lightly on the sections that go through the front panel. The only problem I saw with this design is the nut and bolt area. It wants to spread when tightening the bolts, so I pushed it all the way into the frame (where it should be for starters anyway) so that area can't spread. Thinking back on it, I should have printed those parts solid, I suppose.

Bad on me - I didn't bother checking the Y axis belt attachment before I started this afternoon. It doesn't fit the hole pattern, so I'll come back to that when I can print again.

A question on the frame brace for the middle of the printer. The raised area offset from the centerline of the Y axis looks like it will interfere with the belt attachment. Of course, that will depend on what type of attachment I end up with. It looks like the factory clips will barely clear it. How is it on your printer?

I'll check when I get home tonight, I can't recall off hand.
