Improved Coupler Nut + Wrenches - Ultimate Drybox

This Improved Coupler Nut is a remix of the Coupler Nut from @GunplaMark's The Ultimate Cereal Container Filament Drybox that now includes PC4-M10 Threads and a Flange for a perfect, secure fit with the PC4-M10 PTFE tube coupler. I used the PC4-M10 Threads from @jurassic73's PC4M10 - Tapered threaded opening STEP/STL for design to get the correct pitch and taper for the PC4-M10 coupler threads - increasing the X and Y dimensions of the thread by 2% each to allow hand-tightening of the Coupler Nut to the PC4-M10 coupler. I have also designed two Wrenches to aid in the assembly or disassembly of the coupler: 1 - The Coupler Nut (inside) Wrench wraps around the Improved Coupler Nut 2 - The Coupler (outside) Wrench wraps around the PC4-M10 coupler The Wrenches are optional (but highly recommended) tools that make it much easier to assemble and disassemble the coupler. I also strongly recommend using my Tag Holder for Ultimate Filament Drybox to keep the filament tag (label) attache
