DIY Drilling Jig for convenient 90 degre making holes.

thingiverse

Tried to make usefull universal jig. Can be used to make rather precise holes for furniture and other connections. Plastic is not too strong for such types of devices so I integrated some metal inside (pause the printing, put corners inside, resume). May be next time will put 2 more metal corners inside. U'll need 2 screws 3x30-35 mm. 2 metal corners 60x10 mm (optional) 8 magnets D8xH4 mm a piece of metal ruler ( or U can use the whole long ruler) metal reel or a piece of it ( i used old broken one) I've printed it with different types of plastic. PLA is good for everything except Nuts. PETG is better for friction. There are 2 types of nuts. One for forstner drills (shorter) and one for simple. I'm using 6,8,10,12 mm. Models are included. If U need another size pls write in comments. Sorry, forgot to video magnets and plastic Corners (for ruler positioning) installation. Just, press them inside the plastic. https://youtu.be/zHiffGT4Lvw
