Introduction.

This has been initialy developped in order to have Gridfinity boxes for a few of my flashlights, (CONVOY, OLIGHT, …) but in the end it's of course working for any kind of rounded item (glue sticks, flasks, bottles, any other round flashlights, …).

The basic usage is for “1x1” box (of any height), but more advanced usages are possible as “Do-It-Yourself” (there is one example in the .scad file).

Pre-requesites.

You have to download the “1x1” models from here : https://www.printables.com/model/210548-filled-in-gridfinity-boxes-for-customization/files (it will be used by the script as a basis) and put the proper models from there (= the ones you want to use) inside the same folder than the “.scad” source file (probably mainly the 1x1 files).

Of course you need OpenSCAD.

Generating your own STL files.

In OpenSCAD, configure in the .scad file :

• The proper model name to be imported as a basis (for example, “filled box 1x1x6-hi_b.stl”)
• The exact size of the rounded hole, preferabily measured with a caliper. For examples :
  • CONVOY S2+ = 24 mm
  • CONVOY M2 = 31.6 mm
• The extra margin (still in mm) to be used around that diameter. Will depend of your printer, material, exacts size of the flashlight or bottle, … For example, with PETG, i used
  • 0.5 for “older” CONVOY S2+
  • 0.4 for “newer” CONVOY S2+ and CONVOY M2
• The label, in case you want one

Then just generate the STL file (F6 under OpenSCAD) and export it as .STL, and you'll be ready to print.

Preconfigured STL.

A few preconfigured STL files are available for easy try out. They are all with “0.5” extra margin.

• For CONVOY S2+, with or without label, with gridfinity sizes “1x4” and “1x6”
• For CONVOY M2, with or without label, with gridfinity sizes “1x4” and “1x6”
• For one small 30 ml bottle / flask bought on aliexpress or amazon
• And a curiosity, one 2x2x6 Gridfinity box allowing to contain at the same time :
  • One CONVOY C8+
  • Four CONVOY S2+
  • And one OLIGHT 1iR2 PRO

Printing.

Nothing special, supports probably needed for the bottom holes of the underlying Gridfinity model if you are taking the versions with holes.
