Drink Tank air pump mount and adapters

thingiverse

For gatherings, I don't bother with CO2 for my Drink Tank, but instead utilize a bicycle pump. However, it required three hands to pour a beer, with two hands operating the pump and the third hand controlling the faucet. So, I designed a clamp that attaches the pump to the handle, followed by a Schrader valve connected to a 3/8" hose barb, and then a 3/8" hose barb linked to a threaded connection on the drink tank cap. A groove for an O-ring was incorporated into the adapter for the Drink Tank cap, utilizing a P6 seal. I printed the clamp upright initially, but now I think it would be more robust if printed flat. This approach would necessitate removing supports from the screw holes, which could be time-consuming. To ensure strength, I employed five perimeters and found that it seems sufficient. The clamp requires #4-40x3/8 screws and nuts for assembly. Fusion 360 files can be accessed at https://a360.co/2UGmNmD, https://a360.co/2UDD3EE, or https://a360.co/2ZLDgvx.
