Water Jet Drive - bearings supported shaft

thingiverse

I finally make it to work. Here's a quick edit of a wet test: https://youtu.be/7BdXrHi9DBI All thanks go to ReneeCelDesign for this amazing work, and SafetyComp for the idea of bearings on the shaft. All original files can be downloaded from ReneeCelDesign here: https://www.thingiverse.com/thing:1952400 But for your preference to have bearings on the shaft, here are those files: * Impeller with smaller hole for 4mm shaft * Inlet with bearing hole for 5mm shaft * Inlet with bearing hole for 4mm shaft * Stator file with hole for bearing * Mounting flange for the back of the boat * Inlet filter * Washer between impeller and bearing inside stator (not really necessary - I find it better to cut two 2mm long washers from brass Presta bicycle valve - one for each side of the bearing) I also repaired a small hole in the original inlet file in both my files (hole is visible red in the screenshot) - I noticed this when I already printed it, so mine printed part still has a hole, but yours can be better. You will need two bearings: 105 2RS for 5mm shaft (5x10x4mm), or two 104 2RS for 4mm shaft (4x10x4mm). I printed the impeller with PETG from Plastika Trcek and all other parts with STRONGMAN PLA from Azure Films (something between ABS and PLA by characteristics) all in 0.12mm. Filter and flange were printed from PLA... and the second impeller with a 4mm hole also from Strongman, now. I stretched 32x3.5mm O-ring over the stator channel for the flange mount.
