HDX (or Hypertough / Hyper Tough / Anvil) Organizer Box Inserts (FreeCAD Parametric)

Update 2024-02-09: apparently the mold for these organizers has been updated with a reinforcement rib behind the latches. I've created a new folder (Hypertough Slot 16 & 17) with bins that have cutouts to avoid this rib. Thank you @bdpickett_645001 for pointing it out, sending dimensions, and running a test print to confirm these fit the newest version!

Update 2023-01-17: replaced Slot 1 Top Half 2x1 with correct STL.

Update 2022-12-28: replaced duplicate 1x2 STL with correct 2x1 STL. Added Slot 16+17 3x2 top & bottom STLs.

HDX organizers are incredibly cost-effective (usually $10-$12 US for a pair of organizers) for medium-sized parts, but aren't nearly divided enough for the smaller parts that I've been purchasing for 3D printing lately. I designed these bin inserts to remedy this problem, as I wasn't satisfied with the few other options I found elsewhere.

For each size/type of slot, there are a lot of different configurations available. See the ASCII image reference for how the slots are numbered. For each slot: if you want to stack a pair of shallow bins, choose a top and bottom half in whatever divided or undivided configuration you'd like. For a full-height bin, simply choose your divisions. Divisions are in XxY format: number of compartments along the X axis by number of compartments along the Y axis.

I have included the FreeCAD files used to generate all of these STLs, and did my best to make these parametric. If you need a different configuration of divisions, or even want to try stacking these 3 high in one slot, then you should only have to edit the parameters in the spreadsheet for the relevant slot using RealThunder's branch of FreeCAD at https://github.com/realthunder/FreeCAD/releases

Printed at .28 layer height for speed. Include enough walls to make sure your box walls won't be hollow. Variable line width recommended for these thin(ish) walls.
