Playing Card Shuffler v3

prusaprinters

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 DixitNo glue needed for assemblyIt 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 sourceNotes 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 heightSupport 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 assemblySee 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.
