Print guidance estimate

Uses saved filament metadata

Print cost & setup estimate

Setup guidance plus saved or slicer-confirmed filament, cost, and time. Model file size is never treated as printable volume.

20 model files

Recommended kit

50g

Based on 25% main infill across listed model files

Material cost

$1.20

Filament only at roughly $24/kg PETG / ASA

Print time

2.0h saved / 1.4h–2.4h estimate

Uses 70 mm/s, 0.2 mm layers; verify supports in slicer

Description

Update1: I made new crank, its reinforced and its easier to rotate slowly (I made it 3 gearboxes as its relatively hard to rotate whole thing) next step would be to improve planet gears holder as its now weakest part for 3 gearboxes variant. Update2: I added reinforced version of planets holder thingies, they are pretty solid now and I consider this project finished :) https://youtu.be/ytXheS1m-V4 PS i find 2 gearboxes and old crank as best one, 3 gearboxes are cool but too much friction ruins the fun and also more possibilities for whole system to jam... but the choice is yours :) How to assemble (sorry for quiet audio) https://youtu.be/9Z3ExSQPsK8 Hello , I just want to publish my few months worth project :) I don`t know why but I wanted to make mechanical toy, something that can do something while few days ago it was just static filament roll.
