Acetal Carriage Trucks August 10, 2016 04:02PM |
Having decided to rebuild my delta, I wanted to remove as many printed structural parts as possible. I am going to be using the Robotdigg metal corners, carriages and effector. I decided to put my mini CNC to use and make some acetal carriage trucks, (I would like to have these in aluminium, but I only have a crappy 200W spindle and don't think it's up to the job)
I am really pleased with how they turned out The eccentric spacers were a nice snug fit and they run nicely on the V-Slot profile, with absolutely no play. I made the horizontal hole spacing 31.5mm (slightly less than the V-slot metal carriages, which are 31.9mm) The vertical hole spacing is 45mm, which I am hoping will give then good stability.
The 4 x M3 mounting holes I countersunk 2mm deep with a 6mm drill, and fitted M3 x 20mm countersunk screws and nyloc nuts to hold the 2 parts together.
I have attached the stl as they could also be printed.
Regards,
Les
