BT40 Tool tag

This is my take on a BT40 Tool Tag.
There are several other designs that already exist with most following the general form of a flat horizontal tag. For my application the tools are stored close to each other and the tag would hit the tool next to it meaning the tag needs to be vertical for it to fit.

I went through a few iterations before reaching this design. My first attempt had a label holder where you could insert some paper / card however it wasn't durable enough with it easily breakable. That is when I came up with the idea of a 2 piece design, After a few iterations I came up with a profile that felt nice, was easy to put on and take off. I did trial heat set nuts however they are more expensive and need more tools / time to install, there was also more risk of installation error so I changed to hex nuts. I then made it a bit more compact so it should work with 70mm or above grid spacing. Lastly I made the front a little bit wider to accommodate 66mm wide labels.

The 3d printed part is quick to print at under 5g of filament per each at 15% infill, 9 fit on a K1 print bed and likely on other small build plate printers also. Standard M3 hex nuts are then pressed into the two front sections. You may need to use a flat blade screw driver or similar to press it to the bottom of the pocket.
From there they can be customised for your needs. There is space for a 66mm wide tag, hole spacing is 52.6mm following the arc, 4mm up from the edge.

What you use for the actual tag portion is obviously up to you. I envisaged a 6cm wide x 4cm tall tag however the latest revision is to accommodate the use of 66mm wide laminating pouches (you could go wider but they may overhang the main curved section). They are readily available in dimensions like 66mm x 95mm which would allow for one very tall label or cut it in half to make two.

I have yet to implement these into the workshop, I have test fitted them however advisable to print a test one first before you print off a heap. Design files are included to allow to easily changing nut size ect.
