Open-Source 3D-Printed G-Scale Rail Bender

I have considered to purchase a rail bender for a long time, but i find prices of commercial solutions unfriendly. So I found well-known GitHub - PRouzeau/Garden-train-G-track-bender: 3D printed Garden train "G" track bender and decided to give it a go.

Printed on Bambu H2S in PETG, 100% density, 5 walls everywhere. Hardware (BOM is on github too) come from amazon at a cost about £30. Could be got cheaper offline - but I just don't have a decent hardware store anywhere near.

I have filmed assembly and operation - and so far I am satisfied - it does it's job perfectly well. Can't comment on longevity - but worst case scenario I can re-print it in ASA filament - that will make it much stronger.

Here is a footage of assembly and operation.

Very good demo, often forgotten that a railbender also unbends as you say. A use for all those unwanted R1 curves to turn them into straights, once the clipped in railjoiners are removed as you have 1 rail can be taken from each of 2 curves to make to slightly different straight sections if that is required, or as in your case replicating a larger curve. You should have them in the shoos for Easter!
