UPDATE 31/12/2015 Added a US version for 23.5 conduit
This is a first release of my Universal Mount for the great Mostly Printed CNC.
For my second build of a MPCNC, i just wanted to have a more convenient way to change tools, and not have to unscrew nuts trap.
I saw this design from Lucan07, and I decided to improve it, by changing its shape to minimize tilt, and adding an optional way to secure tools with 2 or 4 screws, easily removable.
Universal Mount hold in place like other tool mount, with 4 M4 screw with nut trap inside pipes.
Then tools mount can be fitted on two different sliders, witch a call "mini mount" and "maxi mount" depending of the weight of the tool. Sliders have a tolerance of 0.4 with the mount, so the calibration of your printer is an important point before printing it. I printed it with PLA, and the fit is tight, but the sliding is quite easy.
On the back of the Universal Mount there is 4 m3 nuts for securing sliders to avoid tilt or vibrations. The fit of nuts is very tight cause i want it to hold in place between swapping of tools.
On this release there is 4 main files :
- The universal mount itself
- The “mini mount”
- The “maxi mount”
- The “maxi mount” with an offet of 10mm, to avoid tool to touch bearing when Z axis move UP.
I have included STEP file for easy editing, and let people interested adapt their own tool holder.
I will post as a remixe a pen holder, and a friend of mine will post soon a MK8 mount.
NOTE : this is for International version of MPCNC, but if requested i can adapt to other version.
