A full line of all size bins for the "20 Bin Medium Portable Parts Storage Case" and "15 Bin Small Portable Parts Storage Case"
Bins are designed for fast printing without supports. The registration tabs (feet) are replaced with screws for durability and structural strength.
Reason for Design: While there are a lot of similar designs I printed several and was unhappy with the fit, or inability for the bins to work in both models. This set covers all sizes and is compatible with all 4 boxes.
An effort was made to make this box fast and easy to print, while being strong and robust as they are going to hold heavy nuts and bolts. There are 2 versions of the HF Parts boxes that look similar but have different internals.
NOTE: Harbor Freight sells this same box under two part numbers. Both boxes are slightly different internally. The inserts were designed to work in both, but are more ideal for #62778 – They will fit #93928 but are tight in the front sections around the handle.
