These piano key dip blocks are used to measure how far a white piano key drops when you press it down. The keys have to be leveled before you do this.

KDB1232 - 12/32" = 3/8" = 9.53mm
KDB1332 - 13/32" = 10.32mm
KDB1432 - 14/32" = 7/16" = 11.11mm

Check your print with a caliper and scale the height in your slicer if it needs to be adjusted for accuracy. Most home printers are not 100% accurate.

Use a high print quality so the angled part will print as smoothly as possible.
