MPCNC Tool Holder Nut Trap for 19mm ID pipe

I needed MPCNC Tool Holder Nut Traps to suit my 19mm ID (25mm x 3mm wall thickness Aluminium pipe), and the stock units were too big (designed for 1mm wall thickness by the looks).

Just printed two of them and they fit nice 'n' snug (usual deal with cleaning out the holes with a 4mm drill bit, and sanding/scraping off the flattened first layer). I have not designed in any clearance for the nut traps as I wanted them to stay put. The nuts pull in fine using 4mm screws.

Hope someone else finds them useful.

Notes:

I print all my parts with MatterControl, using a 10-15 loop skirt (touching) to ensure good adhesion. I'm printing using PLA directly on to cold glass smeared with a 10% wood glue (PVA) / water mixture (allowed to dry completely).
