/diy/ - Do It Yourself

I just got everything working today, after printing the benchy tugboat (not perfect but satisfactory) I got in Fusion 360 and made this plug thing which will hold my flash drive inside this metal keychain cylinder.

It took a lot of iterations to get the right dimensions for a friction fit between all three components. I wasn't able to get it perfect even after 8 tries, the friction is greater between the flash drive and the holder than between the holder and the cap, so pulling the flash drive out also pulls out the holder. I may secure it with adhesive instead of relying on the friction fit.
It seems I just can't get dimensionally consistent results with my printer. also, the inner corners where the flash drive slots in are always rounded, despite being sharp in the model. I'm not sure if this can even be fixed, but I had to increase the width to accommodate that slight narrowing (the flash drive has sharp corners).
