I use Bosch radiator thermostats, last year or so, the valve broke off from the radiator, it broke at the mount, a number of the holding clips broke, I suspect this was a gradual issue over time (maybe it was over tighted when originally fitted, or corroded trv, not sure).
Anyway with winter approaching, I wanted to regain control of the radiator, so equipped with a range of Torx screw drivers, my trusty callipers and with Fusion open, I disassembled the unit and I modelled up a replacement.
Initially focussing on the fitting of the internal components and ensuring it would correctly mate to the existing motor housing, I initially ignored the mounting to the radiator (The part that actually broke). hence some photos don't show this.
I also needed to determine the thread/pitch of the drive actuator shaft. For which I printed (and included) a test piece to ensure my printer would create the thread and the worm like gear would operate.
After designing the main housing and performing a test fit. (it fitted perfectly the first time!). I then modelled the coupling, replicating the original design. Initially thinking, due to the way I'm likely to print the part, the layer lines would not help with overall strength and would lead to failure. So rather than printing the entire part, I simply split the model and printing the lower section to allow a test fit and confirm if they would break when fitting the nut. To my surprise, it didn't. (I had to break one to remove it) I have also included this model.
I have since printed the entire part, transferred the internal components, added a bit of grease and fitted to the radiator. The thermostat has completed the calibration step and I've operated the valve a few times without failure, however YMMV. I expected to have to reprint in the. future, maybe with a stronger material (currently used PLA+ )
Once printed I needed to open up the holes, external mounting 2x2.0mm and internal gear 1x1.5mm
Remember, tighten the thermostat to TRV by hand.
Modeled in Fusion
Printed on BambuLab P1S. (although will likely print a new version in PC on Prusa MK3)
printed at 0.24 layer height. used tree support
