About this model

Still W-I-P. Sharing because comments on the original asked for some of these improvements, and because several things changed from Quintox303's design: 1. Added the D 2. Pins/holes to locate the letters accurately. 3. Two-part base for printing on smaller beds 4. Improved E- and S-gear axles Updated but not yet printed by me (7 Feb): 1. Improve the E- and S-gear axles more... they're still weak. 2. Chamfer bottom of D, E and S and top of C, L, and R main gear Still to do: 3. Thicken E- S- and sun-gears 4. Add small bearing surfaces to base to lift gears off base for reduced friction 5. Move main axles slightly (3-4mm?) closer together to reduce play 6. Stops to stop rotation when in correct alignment. 7. Increase base size behind the D 8. Increase height of main axles
