Tower Fan Bearing Bracket
Created today
Description
What it's for
A custom replacement L-bracket designed to hold a 626ZZ ball bearing at the top of a cross-flow fan rotor in a tower unit. Built to secure the 6mm fan shaft while maintaining precise wall clearance.
Dimensions
- Arm Dimensions: 54mm x 44mm footprint, 5mm thick.
- Wall Face: 18mm total height.
- Mounting: Two 4mm screw holes, spaced 28mm apart horizontally and centered at 14mm from the base (4mm from the top of the wall face).
- Bearing Seat: Sized for a 19mm OD bearing, dropped 3mm below the main flat surface, featuring an open top for drop-in installation and a 12mm clearance hole below for easy push-out removal.
Print notes
Because the bearing housing now protrudes 3mm past the bottom of the main arm, the model is lifted so the lowest point rests on the print bed. You will need to enable supports under the flat arm, or rotate the part manually in your slicer if you prefer a different print orientation.

Wall Vent Fan Adapter
A custom transition duct that connects a rectangular wall vent to a round inline fan port. The geometry funnels air 90 degrees upward into the fan while maintaining a smooth internal path to minimize turbulence and noise. Features included: Inlet: 360x210mm rectangular opening with a flat back. Outlet: 157mm internal diameter socket positioned 116mm outward and 250mm high. Mounting: Six countersunk holes for #6 wood screws on the top and side flanges. Sealing: Integrated channels for foam tape on the rear of the flange and the underside of the bottom foot.
Inline Fan Duct Adapter
A large, wedge-shaped adapter designed to redirect airflow from a standard rectangular wall vent up into a wall-mounted inline duct fan. Wall Interface: Features a 400x230mm mounting flange that sits flat against the wall, dropping flush onto a concrete footing at the base for structural support. Airflow Path: Converges a 360x210mm rectangular intake into a 6-inch (157mm ID) straight-sided vertical socket. All internal corners are filleted to prevent sharp airflow turns, minimizing stall and turbulence noise. Sealing: Includes an 8mm foam tape channel around the back of the flange and a 12mm channel under the bottom foot to ensure a tight seal against both drywall and concrete. Mounting: Six countersunk holes for #6 wood screws keep the fastener heads flush with the internal flow path.
19mm Cross-Hatch Cane Tip
A replacement tip for standard 19mm cane tubes. Designed to be printed in stiff TPU, this part replaces worn tips to eliminate floor clacking and restore grip on wet surfaces. The part features a solid tapered body and aggressive bottom channelling to handle regular outdoor and indoor use: Mounting socket: 19.5mm inner diameter and 25mm deep, featuring an entry chamfer to guide the tube. Base profile: 40mm wide contact area tapering directly to the upper shaft. Tread pattern: 4mm deep and 3mm wide cross-hatch channels to displace water and maintain floor contact.
8.5mm Rod Square Drop-On Sleeve
Square profile sleeve that slips onto a toilet roll holder rod to increase rolling friction, deterring toddlers from unspooling the paper. Fitment: 8.5mm diameter holder rods Outer Profile: 25x25mm square, 90mm tall Installation: Direct drop-on over the existing rod Note: Make sure to check your holder's rod diameter before printing. Prints upright without supports; PETG is recommended for durability.
1/2" PEX Adjustable Dripper Tee
An inline tee fitting for standard 1/2" PEX, featuring an integrated top-mounted adjustable water dripper. Built to string together in series for garden irrigation loops. Connections: Dual 1/2" PEX barbs form a continuous horizontal run. Metering: A threaded upper cap with an internal conical needle regulates flow rate out of a 2mm orifice. Flow Bypass: Cutaway slots on the stem threads let water escape radially beneath the cap once cracked open. Printing Note: The base requires supports beneath the horizontal barbs to print correctly on the bed.
Garage Vent to 6-Inch Adapter
A custom 2-part venting adapter designed to connect a 360x210mm drywall vent gap to a standard 6-inch exhaust duct. Two-Part Assembly: Splits perfectly down the middle with a 10mm external flat flange for easy gluing. Tapered Male Fitting: Connects securely inside standard 6-inch ducting. Support-Free Print: Internal lofts are designed to print cleanly with no supports while encouraging laminar exhaust flow. Mounting Integration: Six #6 screw holes for securing to drywall, with an extended bottom footing to rest cleanly on a garage concrete foundation.
