Got a sweet Tekno RC kit and struggling to assemble your servo saver? Yeah, me too. I just fought that battle and lost. It was "assembled" afterwards, but the nut was cross-threaded and destroyed. Even better, I mangled all the plastic components trying to take it back apart to salvage what I could.
After the carnage and frustration, I designed this block with a recess to hold the servo saver assembly in place vertically so that I can easily press down on the nut to engage the threads and tighten the spring preload. I used a 17 mm wheel nut T-wrench (just a cheap one from Amazon), added a dab of grease to the nut surface that contacts the spring, and had it assembled and adjusted in less than a minute.
Honestly, it took longer to type this description than to assemble the servo saver. This should fit anything current from Tekno RC as of early 2026, as near as I can tell, the servo saver is pretty universal. I designed it specifically for my MT410 2.0 and my SCT410 2.0.
I designed the block myself, but downloaded the logo from the internet, there's a no-logo version shared too, but I doubt this will work on a non-Tekno part.
Mine was printed in PETG with 3 walls and 15% infill. It worked fine for my builds.
