Differences From The Basic Cherry 3D Printer

Here are some of the changes that I am having to face when trying to build my own version of the printer.

Base Material
About the only locally source of MDF is from the Home Depot hardware store.  I chose to use a 1/2"inch thickness which works out to 12.7mm.  I was able to buy a 2ft x 2ft piece for about $6.  This would be sufficient for the base and any extra bracing I might want to add.

Base Construction
Instead of gluing the base together, I chose to use small wood screws.  Only a few are needed in a few key spots to hold it all together well.

Smooth Rod Lengths
While I was eventually able to source the correct lengths of smooth rod for the printer, I decided to use a set of different lengths to see how they affected the design and construction.  For the X-Axis smooth rods, we have to adjust the width of the base to accommodate for the difference from the 17.5 cm.  With different Y-Axis smooth rods, our bed length will change.  Finally, any differences in the Z-Axis smooth rods have little impact on the overall design.
