Variant construction set

myminifactory

So, this is Variant construction set, which was originally designed about 40 year ago by one Czech company and it is still produced till nowadays:https://www.kaden.cz/variant-stavebnice (please support the producer by buying the original set if you can). It's a LONG time ago since I was playing with it, but I still clearly remember the hours and hours of joy and entertainment it brought, as well as the skills I acquired by building different constructions.Recently I got into possession of one of these original sets and gave it to my son (3yo). He also likes it a lot. And then I realized that with 3D printing I can create more and new parts, limited just by my imagination. So I recreated most of the original set in SCAD and added a lot of new parts. From the original set I only did not try to model the chain gears since the chain consists of quite small parts and would be difficult to print accurately enough. On the other hand, I added many different gears to the original ones (12T, 24T). For quick overview see: Part list with print instructions.pdfFor ideas from the original set see: Variant - original manual.pdf GearsNot all gears are compatible, the rule is that the sum of teeth of both gears must be multiple of 18.e.g. 12T + 24T (1:2 ratio) = 36T = 2*18. The multiple will also tell you how far apart the gears are placed. In the example 2 holes apart.I prepared these gears and combinations:6T + 12T (1:2)12T + 24T (1:2) - the original gears9T + 27T (1:3)6T + 30T (1:6)6T + 48T (1:8)Worm gear + 24T (1:24)Worm gear + 6T (1:6)You can also make many more combinations using the attached SCAD file. Regarding other, non-printable parts:8 mm wooded rods (original lengths are 12 cm, but this is up to you). I buy beech wood rods 0.6 euro per meter from my local hardware store. Only remark: check the diameter with caliper when you buying it. I found that they can way piece by piece from 7.7 to 8.3 mm. For me 7.8-8.0 mm fits the best the holes of the threaded clamps.I would toss in a few M8 washers for when you want to reduce gears side friction.Also a few 8 mm ID o-rings are handy for adding friction to when needed. Last words: I plan to extend the set of components in the future. In that way I'm also open to your suggestions. And I'm also looking forward to you creations :-)
