Screwball with tighter thread

thingiverse

I've uploaded an enhanced remix of this here: https://www.thingiverse.com/thing:3119518. For me personally, the thread on the original is woefully inadequate – I could push the two halves together instead of screwing them together, so this is a refined version with the inner thread enlarged by 1mm in diameter (resulting in +0.5mm radius). Still very much JamieLaing's design, just fine-tuned slightly. Printed at Seaside 3D, UK – check out their website at www.seaside3d.com
