Playing Card Shuffler v3

Update 18. 4. 2023: added 68x44mm card version (print big wheel 2x - there is not middle one). I don't have small cards and confirmation it works fine - please see discussion) ----------------------------------------------------------------------------------------------------------- Based on my year experience with my v2 model and ideas from its remixes, I have create a new version with following enhancements: - Two card size models:- 93x71mm for Terraforming Mars, Archa Nova, Mandala, … - 125x82mm for Dixit

- No glue needed for assembly - It can be disassembled (I do it when travelling so the shuffler does not occupy a lot of space). - Adjusted shafts for better card movement, raised plates a little (but not much as in some remixes because then I had issue with stuck cards in the middle). - Card blockers have tracks to better stay in place. - Plasti Dip variant for shaft. - Increased stability of shuffler so cards on just one side would not flip it. - you need https://github.com/BelfrySCAD/BOSL2 if you want to change .scad source

Notes for printing: - I've printed it with 0.6mm nozzle and 0.3mm layer height but it should be fine with default 0.4mm nozzle and 0.2mm layer height - Support is needed for card blockers and handle. - Brim is needed for shafts. - O-ring for shaft variant are 2mm thick, outer diameter 18mm, diameter size 12mm. I use water pipe seals - e.g. https://www.hornbach.cz/p/plastove-tesneni-k-prevlecne-matici-1-2-12x18x2/8463732/

Notes for assembly - See video :) - Make sure smooth part sides (from printer bed) touch cards (especially for shuffler sides and plates) - cards need to easily slide on them. - To set up proper card blocker position, I use small card deck and set blocker to a position where it allows just one card through.
