This is a reworked update of Things 614962 and 652717.
The geometry has been corrected to give a more truly linear output, and some fixing points have been enlarged for greater robustness.
A complete set of stl file have been uploaded here.
The model is based on mechanism 329 from 507movements.com.
Designed in Moi and made in PLA on an Ultimaker 1.
Resolution: 0.2 mm layers
Generally I design holes in which something rotates to a nominal dimension such as 6mm diameter or 8mm diameter and the male parts about 0.3mm of 0.4mm under nominal.
Post printing I use hand reamers to bring the holes to the correct size and roundness.
