PL-259 And BNC Double V-Jaw Coax Wrench
This is a flat 153 mm double-ended wrench with a 60° V-jaw at each end. The large jaw is 28 mm wide at the mouth and wedges round or hex coupling nuts from about 10 to 26 mm, which covers PL-259/SO-239 and N connectors. The small jaw is 16 mm wide and takes about 5–14 mm, for BNC, SMA and F connectors. Because the V grips by wedging, no exact nut size is needed. You can snug and loosen coax at an antenna or radio without crushing the knurl with pliers. It prints flat, 8 mm thick, so the turning load runs along the layers, and it has a 5.5 mm hole for hanging it on a peg.
Ferrite Toroid Five-Size Stacking Rack
A 142 x 46 mm bench rack with five pegs, one per common toroid size: FT-37 (9.5 mm OD), FT-50 (12.7 mm), FT-82 (21 mm), FT-114 (29 mm) and FT-140 (35.6 mm). Cores stack up to 36 mm high on each peg, and every peg sits in a shallow well 2 mm wider than its core, so you can grab the size you want without digging through a loose drawer.
SDR Dongle Upright Antenna Stand
A weighted 90 mm base with a 55 mm tall sleeve that holds a USB SDR dongle (anything up to 32 x 17 mm in section) upright, so a telescopic whip on the MCX/SMA end can't pull it over. The USB extension cable's socket sits on the desk inside the open-bottom sleeve and leaves through an underside trench. An M3 heat-set insert takes a nylon thumbscrew that clamps thinner dongles. Three 4.5 mm holes let you screw the base to a shelf.
HT Radio And Speaker-Mic Belt-Clip Dock
This desk dock is 140 x 80 mm and has two upright tongues. Your handheld radio and its speaker-mic hang on them by their own spring belt clips, so the dock doesn't depend on any one radio body size. The radio tongue is 4 mm thick (60 to 44 mm wide, 61 mm tall). The mic tongue is 3 mm thick (36 to 28 mm wide, 46 mm tall). Both have a lead-in at the top. A rear notch routes the mic cord, and four 4.5 mm holes let you screw the dock to a shelf or desk with M4 or #8 screws.
Flexure Sideswiper CW Morse Key
This is a one-piece single-lever sideswiper ("cootie") Morse key for ham radio. The key lever swings on a 1.8 mm printed flexure blade that bends sideways in the XY plane, so no bearings or springs are needed. Two contact posts take M3 brass heat-set inserts (4.0 mm bore) on a horizontal axis. M3 contact screws with lock nuts set the gap to an M3 screw and nut pair through the lever's 3.4 mm hole. A third M3 insert at the back is the common terminal. The 110 x 70 mm base has two 40 x 18 x 5 mm pockets that you fill with washers or lead shot for weight. Put 2 mm stick-on rubber feet under the base so the lever clears the desk.
Universal Toroid Winding Cradle
A bench cradle with a tapered double-V pocket. It holds a toroid or ferrite core upright while you wind it. The pocket narrows from 18 mm at the top to 3 mm at the floor, so it wedges cores about 3–18 mm thick, and the 36° end ramps centre any OD from a T-50 (12.7 mm) up to an FT-240 (61 mm). The winding hole stays clear above the 28 mm tall jaws. It also has a 1.5 mm slit to hold the wire tail, and the 110 x 50 mm base takes two M4 or #8 screws through 4.5 mm holes on a 94 mm pitch.
Wire Dipole Antenna Center Insulator
Centre insulator for a wire dipole or inverted-V: a 140 x 76 mm ribbed plate with a wrap-post cleat on each leg (3.8 mm entry/exit holes for #14 AWG THHN at ~3.4 mm OD, around a 7 mm post) so the antenna tension is carried by the plastic instead of the solder joint. The 42 mm coax tail has three zip-tie stations (3.0 x 5.5 mm slot pairs on 18 mm centres) that strain-relieve RG-58, RG-8X or RG-213, and the top tab carries an 8.4 mm rope eye plus two M4 clearance holes (4.5 mm) for bolting to a mast plate.
Telescopic Mast Guy Ring Plate
A non-conductive three-point guy ring for fibreglass telescopic antenna masts: the 19° tapered bore self-seats anywhere the mast measures 32–50 mm OD, and three 122 mm-span arms each carry a pair of 8 mm line holes so a 3–4 mm guy line reeves through the outer eye and the tail wraps figure-8 around the 6 mm bridge — no cleat needed. A radial 3.4 mm boss takes an M4 nylon set screw to stop the ring creeping up, keeping every part of the assembly metal-free next to the radiator.
PowerPole Dual Panel Bulkhead Plate
A 78 x 44 x 4 mm bulkhead plate that fixes two Anderson PowerPole PP15/30/45 connector pairs through a go-box, battery-box or van panel — each pair slides into a 16.4 x 13.2 mm collar 22 mm deep, seats against a rear shoulder, and is locked by an M3 grub screw in a brass heat-set insert (4.0 mm bore), so it holds regardless of housing length. Four 4.5 mm M4 clearance holes at 64 x 30 mm mount it behind the panel, twin 3 x 14 mm zip-tie slots take the cable strain, and the 16.4 x 9 mm rear window leaves both contact cavities open for loading crimped contacts from behind.
