I do a fair bit of 3D printing and I've gotten into prints that need to be assembled and most models use M3 and M4 screws. This kit has a nice selection of screws and sizes for my needs. I use them in conjunction with some heat set inserts into the plastic. The threads on the screws are good quality and the nuts and washers fit the respective bolts. The only think I'm not a fan of is the case itself. The dividers from the case tend slip out and combine the parts. If the dividers were nicer quality and stayed in place this would be a perfect kit.
