Prusa MK3s to bear 2.1 upgrade

The Kit came with 1 defected part but was quickly resolved by printedsolid.com support team. Kudos! I had printed all the necessary parts before making the transfer so installation was relatively easy and trouble free. It is definitely stiffer compare to original Prusa frame. I thought the movement noise would be significantly lower but the improvements was not as much as I had hope for. Overall it’s an improvement but the money could be better spent else where.

LDO Full Bear 2.1 Upgrade

The quality of the extrusions was much better than those from Ali Express. The only problem was some of the screws would not fit a hex wrench and had to be replaced.

Solid upgrade

While being one of the only places with this upgrade in stock, I'm completely happy with it. My i3 printer is rock solid now and they shipped in no time at all!

Only thing on my printer working exactly as expected.

I've been fighting with my direct to full bear prusa mk3s. The frame is the only assembly that hasn't given me problems.
