1/2" PVC pipe based brace for 2020/2040 extrusion printers (Anet A2/Tevo Tarantula)

These are braces originally designed for stiffening the frame of my Anet A2, but would be suitable for the Tevo Tarantula or really any time one would need to stiffen a 20mm extrusion frame cheaply. These could probably use some refinement, but they've worked well for me so far. I've also included a hold-down for 40mm wide extrusion. The screw holes are intended for M5 cap head screws.
