ended up getting a AM scope SM-3B of crags list for $200 today
Went with Loc-Woyke style rig as they seem popular with 3d printers, and used inoculation loop holders for the arms https://www.homesciencetools.com/pro...iABEgL-sPD_BwE
For some reason the rack and pinion gearing for the syringe holder is giveing me fits, cant figger out how to draw it right in F360, any one out there have a cad file they want to share?
I thought about ordering this STL set https://www.the-beeman.co.uk/instrum...tion-102-c.asp
by they won't sell a cad file, so its a bugger to adjust it to the local hardware ie 8mm to 5/16s
