Lid raiser for K1 Max with roll up/down lid

As a K1 Max owner I think it is a right of passage to create a lid raiser design so here is my effort.  As I have gone down the chain free route and wanted to move my sensor, the rear section includes a removable bracket for the runout sensor that is held in place with a M3 x 6mm machine screw.  The runout sensor itself is held on the plate with the original M3 screws that held it on the frame.

Each section is push fit and then I glued mine in place once I was happy with the final design.  Just try not to place your z seams in the rebates otherwise you will need to de some fettling with a file or craft knife.   

You will need four of the ribs to press into the bottom of the main sections.  I Did it this way as I wanted to experiment with different options.  Again, I have glued the final ones in place.

If you are moving the runout sensor, if you unclip the top horizontal cable cover and carefully clip a section out directly below the sensor, there is just the right amount of slack cable to fit the new position.

I used 3mm self-adhesive rubber to line the top of the riser for the lid to rest on.  I have not done the cut out quite deep enough for that 3mm to run all the way under the rollers though so a 1mm foam may be a better option under the rollers.  

Build in the picture is PLA+ with 4 walls, 10% gyroid infill and 3 top and bottom layers.  I had slight issue with lifting at one end on the first piece which was irritating but I think that is due to a bed issue.  Using glue and a 10mm brim sorted it on the other pieces. I also turned off the side fan for the prints.     

The rollers are slightly tapered but will need a blob of silicone in the gap before you push them in place to keep them in position semi-permanently, but still allow you to take them off when you fancy a change.   The rollers are also marked on one side with a “B” as they are slightly offset.  The B should be on the bottom of your lid.  To get the rollers positioned, put the rear two roughly where you think they should go (with no silicone), put the lid on slotting the rear end into the roller stops and then move the lid into the correct position so the front lines up with the rebate.  Lift the lid up slightly, slide the front rollers on and see how things look in the resting position. when you are happy, put a piece of tape alongside each roller, lift the lid off, add a tiny smear of silicon to the gap in each roller and slide them back on. Put the lid back on in the closed position, push the rollers home and leave the silicone to set.   

This is the cable sleeve I used in the photo in case anyone wants similar
