Sforno on Exodus 36:7/ספורנו על שמות ל״ו:ז׳

1והמלאכה היתה דים, the work performed by volunteers for all spheres of the artisanship and craftsmanship required was adequate for the needs of the project

2לכל המלאכה, for every manner of work required.

3לעשות אותה והותר, in order to complete the work, and more. The craftsmen did not have to skimp on anything for fear that there would not be sufficient materials of the required quality to execute the plan in the best possible fashion.
