WASP clay extruder 19 wrench

If you have a WASP 3d printer, and you use the clay extruder, you must use a 19 wrench to unmount the front tube joint. Standard 19 wrench are big and heavy, so I created this one that is more agile and comfortable.

Print suggestions.
Use 0.4 or 0.35 mm nozzle, 0.2 layer height, min. 4 shells, 1,4 top and bottom thickness and 22% infill. If you place the wrench in his natural position on print bed (see 2nd image) no supports are needed. Add min. 10 brim perimeters in 1' layer if you print
