Marbles
« on: September 02, 2018, 07:36:20 AM »
Since there was some comment with regards marbles dimensions I thought I'd pull this into a separate thread which might be helpful to builders.

Going back into history (and some I have had for maybe as far back as 60 years) they seem to be in two sizes. Whereas older ones are usually clear glass with one or two twist colour through, the newer ones seem to be white glass with three colour red/blue/yellow twist.

These sizes appear to have been maintained through to current production, as I have just opened a pack from:-

PlayWrite, Super Marbles, London, EC2A 3PN, part number No 310-041, barcode 5 016064 006259, bought recently by wife for grandson from a "1 shop" for 69p, containing 15 standard and one large.

The sizes equate to 16mm and 25mm, or 5/8" and 1".  A 15mm ball bearing looks noticeably smaller than 5/8th (as it should!)

Hope this helps.

SO, as far as I'm concerned, a "marble" 3D print that does not take 5/8th diameter is not a marble toy........................ innit....................  :laugh:
