TOMASETTO LPG cap wrench keychain

This handy keychain solves two issues that i encountered with LPG filling valve in my car. Valve cap was always very painfull to unscrew after week of driving (especially in winter). Also mine is always loose without leash that comes with new set. With such a small plug it is certain that it will get lost sooner or later.

So i made keychain size wrench that makes unscrewing cap a lot easier and minimize the chances of losing it.

Print on the socket side with support (from the bed only) and few lines of skirt to ensure bed adheasion ;)
Mine was printed with orange EasyPLA from Fiberlogy just because had it already loaded on my printer but any sturdier material should work great ;) I'd go with ABS if you have enclosed printer

Magnetic feature
Model contains cavity for 7x7x3 mm neodymium magnet for full usage. Little processing needed on the plug itself to make it ferromagnetic so ith kolds inside keychain. I drilled 3mm hole in the cap as deep as M3 screw that i used with chamfer to make it flush. Screw heated with soldering iron is easy to push compleately flush. I used two-component glue to secure it inside the cap. Last photo shows that modification. Will work with any screw that you will find in your thinkering mess 😜 
To use magnetic feature use pause at layer feature to embed magnet inside print, little drop of cyanoacrylate glue prevents from magnet reppeling when magnetic heatbed is used.
Magnet embeding is optional ;) no need to fill magnet cavity in slicer with modifyers if not used.

In the future i'm planning to do remake with a little bit more sleek form factor and maybe ratchet 😇
