Review on PZRT 50 Pack Nickel Plated Aluminum Accessories by Mark Gardner

They all seem to work as intended, although the clearance on the Misumi Series 6 profile is slightly smaller than the nuts when used with Misumi reversible single-lip joints. I created a parametric shim to increase the gap and it helped. Update (December 2, 2020): About a month ago I decided to make some changes to my 3D printer overhaul, replacing the reverse joints with blind corner joints by tapping on my extrusion. While at it I decided to try threading these T-nuts - many of them turned out to be pretty poorly made, and threading really improved the thread quality. I also found that the accompanying reversible brackets were a bit wrong and should have been flat on one side, so the gap isn't a T-nut error.
