This hinged corner will allow you to make MultiGP gates that easily fold up for transport and storage. Now in multiple sizes (500 = 1/2", 750 = 3/4", 1000 = 1", 20 mm, 25 mm, & 32 mm) and with versions that include a straight vertical socket and open 180 degrees. Feedback and suggestions welcome!
Test printed with PLA and TPU. Both work, but the TPU version is too flexible unless it is printed with 100% infill. Others have reported success using PLA for PVC pipe gate joints. So, based on the information available at this point, PLA is probably the preferred material to use. 3 shells with 30% infill in PLA feels pretty durable, but time will tell what is strong enough. Print with the two tubular sections down.
