Description

The original toolrest coming with the machine is not very practical, the fixing screw is under the piece that is beeing worked and the groove always fills up with dust, plus the toolrest area is very small and needs to be adjusted often when working on longer pieces as pens. So I made this one, it has a fixed height, but it is longer, it can stay in place when moving the tailstock, and it is locked from the side. Moving the toolrest is a very fast task now...
On the top, I made a groove to fit a 3mm hss bar that avoid tools to dent the plastic of the toolrest.

The file "StandardLatheToolrest.stl" fits lathes without height modification

If you did modify it's height with https://www.thingiverse.com/thing:3807182, I found more practical to have one for small diameter turnings and one for bigger ones.
If you keep in the same folder the profile1560.scad and the height modification file, you can have a view of the toolrest together with the height increase parts while dimensioning the toolrest.

This is the machine this modification is made for:
Mini Lathe
This is the bar I uses for the toolrests:
3mm hss round bar
This is very useful instead of the little screw arrived with the lathe:
Drive center

I created these links where you can find all common filaments and spare parts at the best prices. These are just links to selected eBay and Aliexpress items, where I normally buy spare parts and materials for my printer, prices are excellent and products are good.
