I was extremely pleased nicely made and designed and a perfect trouble free fit onto the shell's mounting posts.
One of my early Shapeways buys was a chassis by CG Slotcars for a Monogram Lola T70. As buyers, we have to trust that it's designed properly, but as most designers/sellers have limited ranges, there isn't the safety net of a good reputation that a well known brand might have, so I thought it would be worth sharing my experiences and hoping others will do the same. This week I've received 3 chassis from Shapeways, all with problems, and it's occurred to me that anyone with a working knowledge of the software used to create the print files can design a chassis, stick it on Shapeways and sell it to us. I came reasonably late to the party but have now bought several, with varying degrees of success.
3D printed chassis have been around for a while now and more and more of us have started buying them.
