Looks great, I like the idea of saving weight with the 1x transmission. You may have taken the weight saving too far cutting the brake cable so short ;-)
Haha. No weight savings here! All my bikes have had 1X transmission since 2007. I hate front derailleurs.
The front brake cable housing was cut too short out of plain stupidness. But I hope you can appreciate my ingenious way of making it longer: a short extra piece of housing plus two brass end caps resting against each other and a short brass tune holding them together.
That was an option yes but I thought about it but gave up on the idea. Too much custom work as there would be hole left under the hoods and who knows, maybe some day I am ready for a FD!
The sarcasm is interesting but I'd say you're probably well aware that there are plenty small businesses out there which can print such a small object for a reasonable fee. https://ajatec.fi/3d-tulostus/
