Industrial Flat-Plate Oxygen Cylinder Wrench
Created 4 days ago
Description
A flat, plate-style take on the Allied 66080 oxygen wrench, pared down to an industrial silhouette: twin round socket heads at one end, each stamped with its letter, and a chain slot at the tail. The D socket sits in the end head and the E socket in a second head beside it — both rectangular now, 12 mm along the wrench by 8.4 mm across, sized around the standard 5/16" spindle that D and E post valves share. The letters engraved on the top face above each socket are the only thing telling the two apart, which is exactly the point. The whole tool lives in a single 5 mm plate, 125 × 30 mm, so it lies flat in a pocket or a kit bag and prints as one piece with nothing to assemble.
Design notes
- D socket: end head, 12 × 8.4 mm rectangle, letter engraved on the top face above it.
- E socket: second round head alongside, same 12 × 8.4 mm rectangle, its own engraved letter.
- Chain slot: oblong, 12 × 6 mm with rounded ends at the tail, sized for a chain or lanyard.
- Flat plate body: 125 × 30 × 5 mm overall, no supports needed through the flat sections.
- Open-end jaw: removed to make room for the second head, leaving a clean two-socket profile.
Thread a chain or lanyard through the tail slot and the wrench stays with the cylinder instead of wandering off between refills — the optional chain is the small detail that keeps the tool where it's needed. Both sockets are built to the standard 5/16" spindle rather than a specific drawing, and the 12 mm socket length is an approximation, so measure a valve flat-to-flat before leaning on the fit.

living room plinth
Two 100 × 100 mm L-sections, 10 mm leg width and 10 mm thick, laid flat and nested together to save print-bed space. Fit and layout One piece sits normally; the other is flipped onto its back and turned so the two interlock with a 1 mm gap. Combined footprint: about 111 × 111 mm. Check before printing: the 1 mm gap needs a bed that prints cleanly at that spacing; widen it if the pieces fuse. Not a fit for beds under 115 mm square.
30x30x8mm Interposer Plate, 1/4-20 Nut Pocket
Square-edged 30x30x8 mm interposer plate with a central 6.6 mm hole for a 1/4-20 stud. A hex pocket for a 1/4-20 nut is enclosed inside the plate and is designed for a mid-print pause: the nut is inserted when the print reaches the top of the pocket, and the remaining layers bridge over it. Plate: 30 x 30 x 8 mm, square edges Center hole: 6.6 mm through, for a 1/4-20 stud Nut pocket: 13.2 mm across corners (about 11.4 mm across flats), 5.8 mm deep, from Z 1.0 to 6.8 mm Pause height: Z = 6.8 mm, then resume to print a 1.2 mm cover Screw holes: three 3.3 mm holes with 5.6 mm counterbores from the top face, 3.5 mm deep Triangle pattern: apex 3.5 mm from the back edge, two front holes 20 mm apart Nut size assumed: standard 7/16 in across flats, 7/32 in thick
30° Tilted 1.75 in Cylinder With Base
A 1.75 in diameter cylinder leaning 30° from vertical, mounted on a flat base plate. The upper side of the cylinder measures 4.5 in from the base to the top end. Cylinder: 1.75 in (44.45 mm) diameter, 30° from vertical, 4.5 in along the top side Base: 0.18 in (4.57 mm) thick, extends 0.375 in beyond the cylinder footprint on all sides Flat underside, prints without supports on the base; the lean is unsupported on the underside of the cylinder, so a brim or supports may help One continuous solid
Tapa cuadrada con agujeros mixtos
Tapa de 180×180×5 mm con dos lados redondeados a la izquierda (radio 10 mm), cuatro agujeros M3 en las esquinas y un agujero de 5 mm. Dos agujeros redondos de 35 mm a la derecha y cuatro cuadrados de 36 mm a la izquierda, en la zona inferior. Ideas para remezclar Diámetro de los redondos (35 mm): súbelo o bájalo según la pieza que deba pasar; la pared entre ellos es de 7 mm. Lado cuadrado (36 mm): ajústalo por separado; los centros están a 42 mm. Radio de las esquinas (10 mm): 5 mm para una curva más suave. Agujero de 5 mm: está a 25,5 mm sobre el centro; muévelo para un pasacables o un pulsador. Combina con: una base o caja de 180 mm usando los M3 de las esquinas (3,4 mm, a 8 mm del borde).
SpoolScope — Filament Remaining Gauge
SpoolScope is a two-part gauge for estimating how much filament remains on a standard spool, made for spools that sit out of easy view in an AMS or on a shelf. The rail hooks over the flange rim; the sliding block rides on it with light detents, so you can push it down until it touches the filament, lift the gauge away and read the result. Raised ticks and numbers plus an unambiguous arrow on the block make the measurement clear without needing line-of-sight while the gauge is in place. Features Two printed parts: a rail with a rim hook, and a detented sliding block. Gram scale from 0 to 1000 g, with ticks every 50 g and numbers every 100 g. Ticks follow filament geometry rather than an even spacing: closer together near full, wider apart near empty. Arrows on the block tip directly toward the scale, and the detents hold the reading after the gauge is lifted off. Hook gap of 4 mm, sized to clear flanges from 2.8 mm to 3.6 mm thick. Dimensions Flange diameter: 200 mm. Hub outer diameter: 95 mm (from a measured Polymaker spool). Full-roll diameter: 170 mm (estimated from a 1 kg PLA roll on a 95 mm hub and a 65.6 mm spool width). Hook gap: 4 mm. Fitting and calibration Sized around Polymaker and Inland 1 kg spools; other brands are worth checking against the hub and flange figures above. The scale can be shifted by a single fixed offset if a first print reads consistently high or low, so a weight check against a known spool is worth doing before trusting the numbers. If the error differs between a full and an empty spool, the hub and full-roll values are the ones to correct. Print notes Both parts are laid out flat on the print plate. The block contacts the filament at its outer edges rather than at the centre, so a reading can sit slightly high; a weight check against a known spool is the best way to confirm the scale.
