BFB Rapman X-Carriage
by ZaphodBeeblebrox, published
It's a printable clone of the lasercut X-carriage parts for the Rapman.
If the brittle acrylic part is starting to crack after years of abuse, why not make a new one out of printer plastic? Copied straight out of BitsFromBytes's original CAD drawings, it's an exact duplicate of the original.
I've got one on my printer already, and it's working just as well as the acrylic one did.
Out with the old, in with the new. Make sure to print it standing up to beat the warp, with infill for the center hole.
