Mini-Split Line Set Wall Penetration Hood
This is an open-bottom wall hood for a DIY ductless mini-split install. It covers a 2-1/2 to 3 in (64–76 mm) line-set hole, and the top of a line-hide duct up to 100 mm wide and 38 mm deep slides up under its open end. The hood is 106 x 128 x 42 mm with 2.4 mm walls. It mounts with three #8 wood screws (4.8 mm bores) through posts you drive through from the front, so you don't need a brand-specific inlet cap from a bundle kit.
Cycloid Retainer Cover Ring
The Ø96 x 6 mm lid ring for the 'NEMA17 Cycloidal Joint Actuator' kit. Its flat underside traps the Ø60 output flange and caps the sixteen 5 x 18 mm steel ring pins. The Ø50.6 bore (chamfered 0.6 mm on top) runs as a plain bearing around the Ø50 output boss. Four M3x30 SHCS pass through Ø3.4 holes on the R42 stack circle and clamp the stack together.
Universal Thermostat Wall Cover Plate
A 150 x 104 mm wall plate that hides the paint shadow, old anchor holes and drywall damage left behind when a big old thermostat is swapped for a small smart one. A 36 x 26 mm centre opening passes the wire bundle and junction box, and 14 M4 clearance holes (4.5 mm) on horizontal 48/64/80/96 mm and vertical 44/60/76 mm spacings let it bolt to whatever pattern the new thermostat's subbase uses; a 5 mm standoff rim with a rib ladder keeps the 2.2 mm face flat against textured drywall.
