This is an insert for 3/4" conduit boxes that is threaded for PG9 and PG7 glands. When used with a Type C conduit box and PG9 gland, it makes a great outdoor case for a Sonoff basic. The box is commonly found in the electrical section of hardware stores and the glands can be found cheap online. If printing in ABS, you may want to scale the print 2% to account for shrinkage.
