Rebar trellis connectors

Rebar trellis are quite popular as plant supports, so I decided to make my own version with the help of my Prusa Mini+. 

The set consists of connections designed to work with 13 mm rebar. The fit is quite snug, but for the T-3way and the Cross-4Way incorporated a standard nut & bolt (M3x8 or M3x10) solution to be able to tighten it down a bit more (note: don't over-tighten).

I've printed with Prusament PETG Orange at 0.2 Quality setting / 15 % infill / 2 perimeters (the parts feel strong enough with 2, but probably safer with 3-4) / First layer speed at 20% / No supports
