My MPCNC showed some significant flex on the four main feet. I wanted to solve this quickly with small amounts of material and without additional hardware, except screws.
It might look kind of funny and when you already modified your corners in some other way or got them low, the aren´t necessary I guess. If you still got most of the original parts, this little gem will help 🙂
Bring the two feet in place, screw them down and the clamp will bring up the tension on the struts.
Files Include modified feet.
My Hobbyking Fabrikator prints just nice but there are times when the build volume is just not big enough. So why not use the capabilitys of the MPCNC for that? I used the MK8 Extruder and mount from Ryan and designed a compact spool holder that uses leftover parts I had from the CNC build. In my case those are two M8 metric screws with a length of 70mm, a nut and two 608 bearings. Combined it looked like this:
The clamp for 25mm tubes is fastened with four M3 *16 and nylock nuts. It can be rotated to aim at the printhead. For now it is available for center holes of 53mm and a width of 53 mm spools.
