Xiegu G7250 Control Head Front Covers (Screen Only, Full Face, Exposed Knobs)

Overview

Three friction-fit front covers for the Xiegu G7250 detachable control head. Screen Only protects the 7-inch touchscreen and speaker grille and leaves every control usable. Full Face closes over the entire front, knobs included. Full Face with Exposed Knobs covers the screen and all the buttons while the five knobs pass through holes. All three press onto the head by hand and hold with crush ribs. No hardware, magnets or adhesive.

On the Air

The G7250 head is a big glass touchscreen on a two-box radio, which makes it easy to move between the shack, a go-kit and a vehicle, and easy to scratch along the way. These covers were designed for all three:

- Shack: Screen Only keeps dust and stray tools off the glass and still lets you operate.

- Go-kit: Full Face protects the knobs and the glass when the head is packed in a bag.

- Vehicle: Full Face with Exposed Knobs keeps the screen and buttons covered while the knobs stay available.

Every version clears the power button with an open window, so a bump or road vibration cannot switch the radio on or off. A notch in the left wall clears the MIC connector, so the cover goes on with the mic still plugged in.

Print Settings

- Printers: Bambu Lab X1C and X2D, 0.4 mm nozzle

- Material: PLA for indoor and shack use; PETG or PCTG for mobile and field use, where heat in a closed car and drops matter. The Screen Only cover shown was printed in PETG-CF.

- Layer height: 0.20 mm

- Walls: 2

- Infill: 15%

- Supports: none

- Orientation: face-down, front plate on the bed, sleeve walls rising straight up. Every hole, pocket, notch and chamfer is designed to print without supports in this orientation.

- Print time and filament: not specified

Bed size: Full Face and Exposed Knobs are 254.2 mm long and need a bed of at least 255 mm in one direction (X1C, X2D on the main nozzle, and similar 256 mm printers). Screen Only is 170.1 x 154.2 mm and fits much smaller beds.

Design Notes

- Fit: the inside is a sleeve 0.1 mm larger than the 250 x 150 mm face, reaching 15 mm back over the case for 10 mm of straight grip. Small triangular crush ribs, 0.4 mm high, bite about 0.3 mm into the casing. A 0.6 mm lead-in at the rim helps it start straight.

- Seat: each cover seats on the head's shallow bezel chamfer and stops short of the flat face, so it never presses on the glass. The outside uses a 5 mm 45 degree chamfer so it prints cleanly face-down.

- Screen Only: the plate sits 2 mm off the face to clear the G7250 badge. It ends at 168 mm, just short of the raised knob panel.

- Full Face: the plate's inside sits 1 mm above the knob tops, which stand 18.7 mm off the face.

- Exposed Knobs: the plate sits 6 mm off the face, leaving about 3 mm of air over the buttons. The four small knobs (14 mm) pass through 17 mm holes and the VFO through a 49 mm hole.

- VFO tab: the small sliding tab below the VFO dial travels in a closed pocket inside the bottom seat, so the bottom edge stays solid.

- Tried and dropped: magnets on the steel bezel (6 x 2 mm discs were not strong enough) and snap clips (the case seam has no step to catch). An early full cover was a deep box over the knobs; it was replaced with designs that print without supports.

- Testing: fit was dialed in with printed test coupons, a perimeter frame and a hole template, before the full covers. The coupon round corrected the face height and the hole positions.

Known limitations: designed and fitted on one G7250 head. If your filament shrinks more or less than PETG, the grip may be tighter or looser than intended. A test print of the Screen Only cover is a quick way to check fit before printing the larger versions.

Makes, remixes and fit reports from other G7250 owners are welcome, especially from anyone running a different filament.
