About this model

If you own a Yeti Rambler drink bottle with the Magdock cap, you will know the exact issue that forced me to create this. When the drink bottle warms up and empties, it creates a vacuum that makes it almost impossible to remove the lid for cleaning/filling. I've had to use multi grips in the past to get it open. There is also very little besides the small trapezoid part that sticks out the side for gripping the cap. Enter, the drink spanner. I'm very new to cad designing but knocked this one out using Tinkercad and it works really well. Don't ask me about infill and settings etc as I have no idea. I printed on a Bambu A1 Mini on the Smooth PEI plate with PETG on Bambu Studio using 0.20mm Strength @BBL A1M setting.
