thingiverse
Introducing Versions 4 & 5 of the water pump. Both are scaled up from the Version 3 and modified to make them about the right size. Original Versions here: https://www.thingiverse.com/thing:4122545 Version 4 has a 19.5mm (3/4") outlet; but uses the Version 3 cover, impeller etc. The pump drive shaft is based on a 4mm bolt. Version 5 has a 25mm (1") outlet. It has it's own size of cover, impeller etc. The pump drive shaft is based on a 6mm bolt. Version 5 also uses a bigger motor, it is based on this one from a local electronics store. https://www.jaycar.com.au/standard-high-power-d-c-motors-10200-rpm/p/YM2776 Both pumps use brass nuts in the lid or cover as bearings. Just drill them out to slightly bigger than the bolt (i.e. 4.2 or 4.5mm for Ver 4 and 6.5mm for Ver 5)
