A reinforced bench dog for the Festool MFT or similar tables with 20mm holes.
Its is designed for printing with ABS or ASA.
The measurement is 20mm but due to shrinkage with abs or asa the clearance fits well.
I recommend to test print 1 piece and test it then scale up or down if necessary, especially using other filament
A M4x20mm screw fits in the middle to have the piece reinforced for heavy duty use but works also without.
There will be also a fitting tpu cover that protects your surfaces and works as anti slip if you place pieces on top.
