A great desk decoration for any (car) mechanic! Perhaps a good gift idea for your favorite mechanic?

I designed this trophy as a thank you gesture for a friend who helped me fix some engine problems that I had with my car.

Required parts to print:

• Base
• Crankshaft_back
• Crankshaft_front
• Piston_body x2
• Piston_clip x2
• Nametag (change the label first)

There is also an optional printable Connecting_clip that was meant to connect the upper edges of the crankshaft halves, as I didn't want to put a screw on the top where it would be visible and I didn't want to use glue. I think it is unnecessary and the existing screws hold the crankshaft halves together nicely. Since this is a very small part, you need to have your printer well calibrated for it to print nicely. You can give it a try, it worked well for me and clipped into the crankshaft perfectly.

I have included a Fusion360 file for the Nameplate. This file includes history for this object and within the sketches you can find a sketch called “Text”. By editing this sketch you can easily change the text on the Nameplate.

I have printed all parts except the Nameplate with a 0.4mm nozzle and 0.15mm layer height on Prusa Mini. For the Nameplate, I have switched to a 0.25mm nozzle as the 0.4mm nozzle was getting a bit too big for the fine text. No supports are needed.

Required screws/bolts:

• 6x M4 30mm countersunk for connecting piston bodies with their clips and the crankshaft to the base. 25mm bolts will work as well.
• 3x M4 10mm countersunk for connecting crankshaft halves. 8mm bolts will work as well.
• 4x M4 8mm pan head for attaching the nameplate to the base. 6mm bolts will work as well.

Edit: added a STEP file of the Nametag. You can try to modify this one in case you have troubles with the Fusion 360 file. I have also included a STEP file of the whole project for easier modifications.
