Stronger Carboy Stopper Clamp

thingiverse

Remix of Carboy Stopper Clamp from @TheWalrus with added reinforcement and 10mm stopper height (increased from 5mm). This modified design builds upon an already well-designed original, with only minor adjustments made to enhance its functionality. The device ensures wet stoppers remain securely in place within glass carboys used for homebrewing. Initially, I printed the Carboy Stopper Clamp as designed, but it failed due to pressure from the stopper trying to come out, resulting in a separation at the thinnest point of the sidewall near the top of the carboy. To strengthen this area, the sidewall is now widened by at least 54% and features an added curve on its exterior. The gap for the stopper has been increased from 5mm to 10mm, which seems optimal for a #7 stopper with an airlock in both a 6.5-gallon and a 5-gallon carboy. It's also recommended that you print this design upright, as it enhances the tensile strength against the upward force of the stopper. If your carboy has a wider mouth than mine or if you're using a #6.5 stopper, consider reducing seal_h in the model to ensure proper fitment.
