I added the Lead Screw upgrade to my Robo3D R1 and then found I had this hole exposing the screw connected to the motor. I was afraid little pieces of plastic can fly in there and damage something.
I wanted a solution but I didn't want to take everything apart to implement in.
So I came up with this quick printing hole cover (3 min max) that is easy to slide on the screw without messing with the thread.
- Make sure you print with the hole facing down
- .3mm Layer Height
- No Support
- 20% Infill (keeps it flexible but strong)
(recommend you scale up 1% to make sure printing excess doesn't mess with threads on lead screw)
I purposely made a small thin first layer and then bridged the second layer to cause that mesh look but also for flexibility. I found when I had a full first layer it would be too stiff to print with PLA.
