So we are using ours on a food printer which as I found out is a glorified 3d printer with an Epson attached to its elevator mechanism. This was to replace a broken OEM part and it's doing just fine raising and lowering that heavy contraption on a daily basis.

I have purchased several items from UXCELL and every time the product has been great quality, shipped promptly, well packaged, and arrived on time. This time was no exception.Recommended

Works, build quality is not perfect, but it holds shafts together.

I ordered two 6mm to 6.35mm couplers. One came in the correct size. One came in the wrong size, 5mm to 5mm. Also, the correct one came in an antistatic bag, the wrong sized coupler did not, not that it matters much but something to look out for. Luckily, the sizes i need could be drilled out easily with common imperial bits (1/4th in in for the 6.35mm and 15/64ths for the 6mm in case you need to do the same). Mine DID come with the grub/set screws which I'm happy about. From other reviews saying they did not, I was worried about that. Overall decent quality. Holes seem concentric enough.

Coupler worked well with 1/4 steel rod.

Nice quality and fit. Note $10 price is for one coupler only. If you have a dual lead printer you can get 2pcs for same price from multiple other venders here. I went with these because I trust the name and it’s a quality part. I will pay closer attention to descriptions next time.

Not that great a quality with burrs on the inside resulting in the coupler not being able to move as freely causing problems.
