Modular 19-Inch Rack Frame

Modular 19-Inch Rack Frame

This is a highly scalable, fully printable start kit for a 19-inch desktop server rack frame. The standard span required for a 19" rack is too large to print on a typical printer, so horizontal beams are constructed modularly using heavy-duty half-lap puzzle joints to ensure structural integrity across a 480mm width. Uprights are provided as modular "1U" blocks designed to perfectly stack, locking into horizontal base brackets. What it's for This framework creates an expandable desktop rack suited for network gear, homelab gear, and audio equipment. The modular upright blocks feature standard EIA-310 spacing and are formed with hollow cavities and 9.5mm square holes meant to natively seat standard M6 rack cage nuts. Dimensions Horizontal clearance: Maintains exact standard internal 19-inch spacing (483mm outer edge, 450.85mm internal opening). Vertical Height per Block: 44.45 mm (exact 1U metric). Longest individual part: At 190mm, the side crossbeams fit diagonally on almost every standard FDM printer, including smaller 180x180mm beds like the Prusa Mini. Required Hardware Because pure plastic structures under tension will deform when housing heavy loads, this design harnesses standard metal rods and bolting for the structural backbone: Upright Backbone: 2x standard 8mm (M8) threaded rods. Thread these down the large circular columns visible behind the rack uprights to clamp your modular 'X' U heights firmly to the base corners. Crossbeam Lap Joints: 4x M4 Bolts and nuts (or equivalent standard machine screws) to bolt down the interlaced crossbeams. Corner Anchors: 2x M4 bolts to lock the outer beams securely into the corner mortises.

19mm Pencil Sharpener Shavings Catcher

19mm Pencil Sharpener Shavings Catcher

This is a custom replacement shavings catcher designed to securely lock onto standard 19mm pencil sharpener housings. Unlike standard friction-fit cups that can accidentally pop off and spill in your bag, this version features a quarter-turn bayonet mount for a reliable, positive lock. The rounded bottom makes it comfortable to hold and easy to slip into a pencil case. What it's for Ideal for students, artists, and woodworkers who need a reliable way to contain pencil shavings on the go. Great for upgrading cheap bare-metal sharpeners or replacing lost, flimsy, or breakable original plastic bins. An excellent travel companion to keep your work bag or art kit clean from messy graphite dust and wood flakes. Dimensions Overall Size: 50mm outer diameter by 30mm overall height, providing plenty of volume for multiple pencils. Mounting Interface: Specifically designed with internal bayonet tabs spaced for a standard 19mm sharpener housing, featuring a precise 19.6mm clearance to ensure a smooth twist fit. Internal Shape: Features a slightly sloped interior base to help pack shavings neatly and make it easy to empty. Remix ideas Bigger Capacity: Increase the depth of the cup from 30mm to 50mm or 70mm for heavy-duty sharpening sessions without frequent emptying. Textured Grip: Add a knurled, grooved, or faceted texture to the outside of the cup for better grip when twisting the sharpener on and off. Different Sharpeners: Adjust the top opening and bayonet tabs to accommodate a larger 22mm or dual-hole sharpener assembly.
