To support all ProMicro variants, the controller size can easily be modified by adjusting the parameters ControllerW (width) and ControllerL (length) on the model - use length of the pcb only, not the full length.
To build a converter, you'll need an MCU (suggested: newer black promicro knockoffs from Aliexpress that have components on the bottom side), a two holed DIN 5 port (such as these, select 5 pin for model F and other DIN5 keyboards), 6 pieces of M2 inserts (OD3.2, L 6mm - can be adjusted parametrically as needed but any length M2 inserts below 6 mm works by default), and 6x8…12 mm M2 screws (recommended to use 10 mm).
The controller does not need to be glued or taped, it stays in place by itself by design.
The converter itself can be hand wired to the controller very easily. Note that at least for Soarer's controller you need to swap SDA to SCL (no idea how it works in TMK). I found the instructions here very helpful.
For IBM enthusiasts, there is a goodie for the top surface as a hidden feature should you upload the .f3z in Fusion 360.
Suggested print settings for PLA: layer height 0,2mm, infill 30%, vertical perimeters ≥3 with 0,4mm nozzle (note: heat inserts), horizontal perimeters so that min. thickness 1 mm (heat inserts on the side too), 210C nozzle and 50C bed. Print file built for Prusa I3 mk 2.5 (Cubic infill, center of bed).
To open the .f3z, go to File → Upload in Fusion 360. To change the parameters, go to tab “Modify” → Change parameters.
