Everything Looks Great

Finally upgrading a pre-2020 printer to a Bear 2.1 printer. All the extrusions beams looks great. Had no problems with the anodization. The included parts are clearly labeled. Found a few t-nuts with no threads or burrs, but that is why you should check them.

Nice Kit!

Haven't actually assembled it yet, but unpacked the kit and it looks great. Parts are machined well and it looks complete. Can't wait to build my Bear!

Excellent kit

Excellent kit, very complete. A few extras of the small parts. Only had one bad nut plate. Love the blue frame.

Awesome Kit

Great Kit. Brought my old MK2 back to life. The kit was complete and all the parts were top-notch. I didn’t think you could improve upon a Prusa much, bur now my MK2 prints as well, if not better than my MK3. Going to order another for my MK3 as soon as the boss approves.
