Very impressed- the items I ordered are guides for Lishi key cutting pliers (i.e. for cutting a key for a lock). I got two different sets/types of guides in case one didn't work out and both were perfect. The cuts (or bitting) on keys have very small differences between them- in this case 0.15 inches- so if the guides are off by a small amount the cuts are wrong and the key doesn't work. The vendor did a perfect job and the guides work great. If you are on the fence about trying Treatstock, give it a try. I couldn't be happier.
The printed pieces are good. The packaging was sub par. A couple of pieces broke. I didn’t show that in the rating but this definitely was not packed well.
Prints were smooth, precise, and affordable. TPU was stiff, not as soft or flexible as I had anticipated. The fault lies not with the printer but with my unfamiliarity with the material specs.
