A set of leadscrew models made for 3D-printing. Recommended to be printed in PETG, not quite as precise or efficient as metal leadscrews but good enough for most applications and especially if you have a 3d printer build project needing tens or hundreds of leadscrews this can be a lot easier and more customizable then the standard ones as it can be scaled stretched and edited. The profiles is optimized for 3d printing so it's not quite as efficient as the standard ones but close and it can be very easily printed cleanly enough to run smoothly. The download contains the nut and screw rods in 1200 1000 800 640 480 400 320 240 and 80 mm as well as 80mm parts that can be assembled into longer ones - and a mirrored one with two 80mm ends.

They all have a diameter of 8mm as well as a lead of 8mm per revolution but all parts can be scaled as well as stretched to change both diameter and lead.
