I started the Scarab scratch build with a 3d scan of the 80's Monogram model. The deck and hull were enlarged 445% and printed in over 20 pieces.
These prints were glued together and finished and fiberglass molds were made. I had a company called Scanman do the scans and stl's. My printer is a Tevo Tornado. The cad program I use is Fusion 360 and the slicer program I use is Simplfy 3D. A slicer prepares the file for printing and directly communicates with the printer. The plastic I used is called PLA...its hard but brittle. I used it for all the parts but for some of the drive components mounting pieces I cast them from resins...
3D printing looks very difficult and intimidating at first...believe me it's not.
If I can do it anyone can...it just takes a little time to learn and an initial investment...you also need a good laptop with lots of ram.

Great idea to add it to the forum...

Also check out a site called Thingiverse...thousands of free stl files and a large bunch of rc boat stuff...

The possibilities are endless!
