Testarossa Water Pump Shaft sleeve

thingiverse

This handy tool comes in handy when replacing the bearings in a Ferrari Testarossa flat 12 engine water pump. It slides over the pump shaft and lets you apply pressure either with a rubber mallet or a solid bar to release the bearing's bond from the shaft. Simple yet effective, this solution gets the job done. To give it some strength, infill as high up as possible; I used a Markforged with 43% infill and four shells, and it worked beautifully.
