Princeton Tec Switch/Point Helmet Light Repair

Princeton Tec Switch/Point Repair Bracket and Battery Cap

The two prongs on my Princeton Tec Switch broke off rendering the whole light unable to affix to any mounts.  I designed this bracket to fit into battery cap cavity.  The mount has integrated prongs so it can twist into the Princeton Tec mounting system.  I experimented with printing this fix as one piece, but for ease of printing and strength, I recommend printing the battery cap and mount separately and just fusing them together with a drop or two of super glue.  Printing this as one integrated piece results in the two prongs being very brittle (much like the orginal design from Princeton Tec).  PLA works fine and I've found the prongs to be more robust on PLA vs PETG.

Finally, I recommend using some form of retention to keep the bracket and the light together without just relying on tension.  Easiest fix is rubber band or a wrap of electrical tape.  I had some heat shrink wrap and that provided a super tight and clean fit.  

It's crazy to me that this $80 light relies on two brittle plastic prongs for it's functionality.  Hopefully this repairs your light.  Also the battery cap is included in case you just need a replacement battery cap.
