A simple customizable tool for two screw-bits to reach narrow spaces. You can use it like an Allen key.

Of course it is a plastic tool, so not as durable as metal. But for normal loads it must be adequate. To toughen it up and hold the bit in place you can screw two m3 bolts in the side as grub screw. You can choose to omit the bottom of the bit tool to make it more adjustable to the limited space where you working in. Downside is that the bit is less secured.

Instructions:

• The insert-size of the bits is measured from flat side to flat side.
• Don't forget to add some tolerances at the bitsizes. These tolerances have already been included in the standard values (maybe too roomy for your taste).

Happy wrenching :)

Update 14-dec-2019: True and false does'nt seem to work in the TV-customizer, replaced it with 1 and 0 where 0 = false. For the rest the scad-file is the same as the first version.
