UPDATE 2021-04-30: Added a simple cap to cover the motor terminals. This is a wide mouth Mason jar lid with mounting holes for a cheap 12V peristaltic pump. I will use this as part of an automated container garden. The pump I used is https://www.amazon.com/gp/product/B075VN1QZM/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1 The pump attaches with M3x12 screws and M3 nuts and washers. The output tube comes out through a rubber ring designed for a nominal 5/16" hole (sorry to mix metric and American units, but it's what I had on hand). Or skip the rubber ring and it will double as a vent hole (personally I did not find this necessary). Lid is a remix of https://www.thingiverse.com/thing:19105 I had some problems with the original wide mouth jar lid STL so I re-rendered it in OpenSCAD and have included that as well.
