Experiment with concealed and slanted platform
NOTES TO PRINTERS:
Original scaling fits size 8USW (~39EU), only uniform scaling reconmended
Print in upright position
4.206t9.33preview.STL is a preview (duh) and NOT intended for printing
Use 4.206t9.33Lc.STL and 4.206t9.33Rc.STL if your printer can print at least 203mm high for 100% scaling, else try 4.206t9.33L.STL, 4.206t9.33R.STL, 4.206t9.33L2.STL, and 4.206t9.33R2.STL, which require 172mm height at 100% scaling.
Reconmended to print in ABS, PLA is possible, but probably structurally inadequate
Open the hole in the bottom of the heel after printing to install a 131x6mm steel threaded rod, keep in mind that these dimensions change when scaled to a different size!
cut the heel core only to size after inserting
Printable in one piece
Infill >30% reconmended
Print support from buildplate only
The fin spanning the heel and the sole is meant to be a custom support, remove after inserting the heel core, before acetone treatment
