Thanks! I was able to press them together with my hands. Fits my strap perfectly and the wheel turns well. The only negative is that it's a bit bulky and I'm afraid of it scratching the guitar when it's in the case.

After confirming that the original parts needed to be filed down, I have uploaded new STLs with gap clearances. I have also reduced the size of the ridge (per michthom's suggestion) and added in a chamfer to the wheel enclosure to aid insertion.

Pressing the parts together will still require a bit of force, so I recommend using a vice. I am adding that to the tools list.

Hi Chris

Just incredible - I was asked to think about a case for guitar picks to put on my son's carry bag THIS MORNING, and your design simply appeared as soon as I looked in Thingiverse. Manifest destiny, or did the Rapture actually take place and I'm (shockingly) among the saved...

However, I was surpr
ised by the solidity of the pieces when printed on the BfB-3000 I'm fortunate to have available at the moment. The tolerances seem pretty tight too, I don't think I'll be able to press the parts together as the wheel (44.5mm) only JUST fits inside the lip of the base (44.1mm), and the ridge is large
enough that I think it'll crack the piece if I try to squeeze them together.

I may try printing the top at a slightly reduced scale, but if you designed this in OpenSCAD, any chance of uploading the original files so I can tweak the ridge/valley to a shallower v-profile?

Cheers
Mike
