Holder for combination wrench (e.g. Proxxon SlimLine)

Wall holder for 15 combination wrenches (6mm to 21mm). Numbers indicate the wrench width, suggested to print in separate color. The Proxxon SlimLine kit fits perfectly. Includes three mounting holes (4mm Spax).  

I printed with a 0.25mm nozzle to improve the number appearance, and included a manual filament change for white numbering. PLA and 15% infill works fine.
