A buyer measured about 20.4 mm on an XT60E-M and said it takes M2.5 screws, while another seller says M3 (search snippets). Measure a delivered part before printing, or slot the two holes over about 24-29 mm. The 16.6 x 8.6 cutout was not checked against a drawing. Ratings: 35 A at 12 AWG, 500 V DC (Amass TDS).

Every datasheet I read calls for a snap-in hole of about 19.2-19.8 x 12.9-13.0 mm: E-Switch RCA1913, E-Switch RA1, Wurth WS-RSTV, and the SHOU HAN KCD1-2P-X drawing on LCSC (bezel 21 x 15, body about 18.6 x 12.3). The stand's 21.2 x 15.2 cutout (cad/turret_stand.py, and the same in cad/turret_box.py) would let the switch fall through. Change it to about 19.4 x 13.0 for a 1.25-2.0 mm panel, or 19.8 x 13.0 for 2-3 mm. LCSC's KCD1 guide gives 21.2 x 15.0, which is the bezel; the design's number probably came from there. Panel thickness: these snap-ins accept 0.75-3.0 mm, but the front wall is 4 mm (WALL = 4.0), so pocket it to about 2 mm around the switch. Ratings: ordinary KCD1s are AC-only. LCSC's guide gives 6 A 250 VAC; LCSC lists SHOU HAN KCD1-2P-X (C5884416, out of stock) at 6 A, while its drawing says 3 A 250 VAC / 5 A 125 VAC. The only KCD1-format part I found with a DC rating is E-Switch RCA1913 with rating C (16 A 30 VDC), which covers 24 V DC behind the 5 A fuse.

On a 70 x 50 mm board, holes 50 mm apart in y would sit on the board's long edges. Generic 5 x 7 cm boards put their corner holes a few mm in from each edge, but no page I read gave their size or position. Measure the board and move the bosses (y pitch probably about 44-46 mm), or mount the board on its edges with clips.

   "notes": "No 3M Bumpon is a 12.7 x 5.5 mm round foot. Closest: SJ5003 (or clear SJ5303), an 11.2 x 5.1 mm hemisphere. It fits the 13.2 mm x 1 mm recess with about 1 mm radial play and stands about 4.1 mm proud, against 4.5 in the model. Alternatively SJ5012 / SJ5312, 12.7 x 3.6 mm cylinders, sit centred but only about 2.6 mm proud. SJ6115 (15.88 x 4.75) is too wide for the recess, SJ5302 (7.9 x 2.2) is too small, and SJ5018 is a 12.7 mm square whose roughly 18 mm diagonal will not sit in the round recess. Update the foot envelope in cad/turret_stand.py (dia 12.7 x 5.5) to the chosen part. 3M sells Bumpons on sheets and rolls, and Digi-Key's per-unit pack size was not readable. The stand is clamped to the bench, so foot height matters little.",
