Started with the model at https://www.thingiverse.com/thing:5877532
Adjusted it to better fit my battery and then to suit a slightly modified USB top from https://www.printables.com/model/436123-diy-18v-makita-bosch-usb-c-powerdelivery-upply-po
Buck step downs were the same SW3518 units used in the other model, obtained from AliExpress https://www.aliexpress.com/item/1005006005888592.html
Included a rocker switch in my model https://www.altronics.com.au/p/s3210-spst-mini-rocker-switch/
And also modified it to use a battery connector available at AliExpress https://www.aliexpress.com/item/1005006105832653.html
I used M4 x 6 x 6 inserts on the USB top and countersunk M4 x 16mm caps to bolt them together.
