This design uses m3 x 4mm heated inserts and m3x8mm bolts for the handle and m2x10mm bolts to mount the base to the radio.
I changed the overall shape and look of the handle and beefed up the base mounting tabs as the original seemed really weak, especially if printed upright, layer orientation was poor.
