Description
************UPDATED 12/25*********** They were too tall and caused potential X-axis calibration issues. It happened to me when I was testing and fixing collision issues with the bearing filament holder I have. When I tried to calibrate the X-axis with the Z-axis at the top there was an error because the X-axis collided with the toolbox and didn't travel its full distance. I imagine it you never try the calibration with the Z-axis at it's full height it wouldn't ever be a problem. But, I fixed it anyway. ************************************************************* I loved both designs, so I just combined them. Then I added the channels for the wire of my LED lightbar (Amazon link. Not compensated, just FYI). I also added the holder to put the light switch in and holes for the wire ties. I had trouble with the corner by the side channel lifting off the bed. I recommend using a brim if you print the one with the switch holder. The first picture shows the extra hole that I use for the USB-C to USB adapter. The next to the last picture shows the wire channel. The last picture shows the cavity in the back wall to stuff the wire in. There is also a version without the light switch holder or any of the wire channels.
