A 3D printer exhaust fan needs only about 10 to 25 CFM for the heat. Fan types compared by airflow and static pressure, plus DIY wiring, kits and bathroom fans.
A 3D printer vent hose should be 4 inches (100 mm). The duct math behind that size, how long the run can be, and flex hose versus rigid vent pipe.

One 3D printer needs about 9 to 23 CFM of exhaust, and 4-inch inline duct fans are rated 165 to 226 CFM. Fan size, filters, speed and grow tents.
Yes, a resin 3D printer needs ventilation: 3 to 6 air changes an hour, or 48 to 96 CFM for a 10 x 12 ft room. Room, enclosure and IPA wash figures.
A 1/72 scale figure of a 1.73 m man is 24.0 mm (0.95 in) tall. How 1/72 lines up with 20mm and 15mm, and the slicer percentage to convert between them.
1/48 is 1.5 times the size of 1/72 and about 3.4 times the volume. How 1/35, 1/144, 1/76, 1/100 and 1/64 compare, with a Spitfire and a figure at each scale.
Marvel Legends is 6-inch scale, or 1:12. Black Series, G.I. Joe Classified and WWE Elite are 1:12 too; NECA is about 1:10, Hot Toys 1:6 and JoyToy 1:18.
Barbie is 1:6 scale (playscale): an 11.5 in doll for a 5 ft 9 in woman. Furniture sizes at 1:6, American Girl at about 1:3, and the slicer % for doll prints.
Bolt Action is 28mm with 1:56 vehicles; Konflikt '47 is 28mm too. Flames of War is 15mm (1:100). The slicer % to move a tank file between them: 56% or 178.57%.
D&D is 1:60 scale: one inch on the grid is 5 feet, and minis are 28mm. The space and base for every creature size, Tiny to Gargantuan, in inches and mm.
Dollhouse furniture is 1:12 (1 inch to 1 foot) as standard; 1:24 and 1:48 are the smaller scales. KidKraft, Calico Critters and Rolife, and the slicer % to print.
Hot Wheels are 1:64 scale, and so are Matchbox cars; Hot Wheels XL is 1:43. How far real castings stray from 1:64, and the sizes to print 1:64 garages.
HO is 1:87.1 on 16.5 mm track. The ratio and track gauge of N, O, OO, G, Z and S trains, with figure heights and the slicer percentage for each scale.
Star Wars: Legion has no official scale; reviews put it at 28mm to 35mm, about 1:49 to 1:62. Shatterpoint is 40mm (about 1:43) and X-Wing is 1/270.
