As I don't want to use both an allen key AND a wrench when levelling the bed, I made some bumpers to hold the nuts.
The extruder is a modified version of Kuro's extruder on thingiverse. I made it fit a quick coupling that was bought along with the PTFE tube. I really like that I can use it for 1.75mm and 3mm as I an exchange the coupling.
Some protection for the heat bed cables came in handy. This is the 7*7mm size
The e3d hot end mount I designed for Prusa i3 with mount for 40mm ring light (seen in mirror) and mount for 30mm fan. A 5015s fan can be added in the front as well.
