One of the quick release levers was broken on my lawn mover. Here's the spare part. Fits perfectly on my Stiga Combi 50 S AE.
I used a support enforcer in PrusaSlicer to print the part, like shown in the pictures.
I printed mine in “Das Filament PETG” at 0.2mm layer height.
To assemble it, i used a M6x40mm bolt and M6 nut.
