25mm Square steel tube joiners and mounts

PLA mounts and joiners for 25mm Steel Square Tube. Mount blocks are 21.5mm in size. Various types. I have not used them all or printed them all. But a couple such as the center mount with gap have and center mount proved useful in building a canoe rack for my trailer. I'm still learning the CAD (Shapr3d) so they are a bit rough, hopefully you can find a use for them too. They will also fit 25mm Aluminium square tube (although the size required there is 1mm larger at 22.5mm).
