I was tired of fumbling and having many close calls of dropping the engine while showing it off to friends so I designed this nice rotating display stand for this wonderful LS3 engine "ericthepoolboy" designed.

I printed the stand base, engine mount retention washer, 4 motor mount spacers, and engine mount all at 90% infill and a .3mm layer height for maximum stiffness to keep from it flexing while holding the weight of the engine. The support stick will need to be printed with supports and again with a relatively high infill to keep from flexing, ( I did 90%). You will need four M4 x 30 screws to attach the engine mount to the engine, two M3 x 20-25mm screws to mount the support stick to the base, and two more m3 screws ( about 20mm or so) for the back washer that keeps the motor mount from backing out of the support stick.
To assemble, fit the support stick into the base, then using a 3/32 drill bit, drill through the 2 pre-printed holes through the base into the support stick deep enough to fit the 20-25mm m3 screws. Next, mount the engine mount to the engine with the four m4 screws while using a printed spacer on each screw (you may need to tolerance the mount screw holes to fit the m4 screws depending on your printer). Lastly, fit the hub on the motor mount through the support stick ( some sanding may be required, but you do want it slightly tight to hold the engine in a specific position as you rotate the engine around). Using that same 3/32 rill bit, retolerance the center hole on the engine mount hub for the other m3 screw, screw the back printed retention washer to it, then drill one last hole through the printed hole in the back washer into the hub and screw the last m3 screw into it. You're all set, enjoy your new beautiful display piece!
