Aside from the routine hammer, cordless drill, screw drivers, etc there have been a few “specialty tools” that I have found invaluable.
In first place has to be the Prusa i3 Printer that I bought in kit form just for this project. After two-day build and a bit of a learning curve it’s been a fantastic addition.
Second place goes to the Fusion 360 CAD program which has been surprisingly easy to learn and use. I have used it to design several parts from scratch, modified others and closely inspect (inside and out) various PacificMeister provided build files.
Third up is my cheap digital caliper which I have used countless times to precisely measure all manner of things related to this project.
And finally are my set of hex (allen) t-handle wrenches used to drive the countless hex screws on my build. Infinitely better than those L-shaped allen wrenches.
What are your favorite tools?
