Drill depth stop used to drill multiple holes at the same depth easily.

The default settings are for CHC M3 bolts but the parameters can be tweaked for any drill bit size and any bolt size in Freecad.

Note: If you want other sizes and don't want to use Freecad, feel free to ask me in the comments.

Update

2024/05/31:

• Simplified formulas in Freecad to be more coherent with different sizes.
• Simplified geometry to avoid the usual glitches with fillets when tweaking parameters.
• Higher resolution in exported STL files.

2024/12/05:

• Add half sizes in the files.
