Maker Circle And Hex Nut Drafting Template
This 170 x 70 mm drafting stencil lets you sketch enclosures, brackets and panels at 1:1 scale. It has circles from 2 to 14 mm, 1:1 outlines of 624, 625 and 608 bearings (13, 16 and 22 mm), and outlines of M3, M4 and M5 hex nuts (5.5, 7 and 8 mm across flats). Each opening is cut 0.6 mm over nominal so a 0.5 mm pencil traces the true size. The circles have centre-line notches, one edge has a scale notch every 5 mm, and two raised rails underneath hold the stencil off the paper so ink doesn't smear.
8 mm Bore Print-In-Place Flanged Roller Bearing
This two-bolt flange bearing prints as one piece. Six 12 mm double-cone rollers sit trapped in a V-race between the outer ring and a locking inner hub. The hub has an 8.3 mm slip bore for 8 mm rod and an M3 grub-screw collar. The flange is 104 mm long with M4 holes on 80 mm centres. Use it as a pivot or lazy-susan bearing when you don't have a steel bearing to hand. All the running gaps are 0.5 mm, so the part comes off the plate ready to spin.
608 Bearing Reducer Sprue Set
A snap-off sprue of eight flanged reducers. Two 22 mm OD sleeves hold a 625 bearing (16.05 mm press bore) and two hold a 624 bearing (13.05 mm), each in an existing 608 pocket. Two 7.9 mm OD bushings with 3.4 mm bores and two with 4.4 mm bores let 3 mm or 4 mm shafts run through a 608's 8 mm bore. You can reuse 608 housings, wheels and pulleys for small gearmotor shafts without redesigning them. The whole frame is about 113 x 41 x 8.5 mm.
