Nut traps moved further from the edge of most parts. Fixed ribbon clamp slots too deep. Modified for JHeadMK5. Changed bed thermsitor type. Extruder block is now thinner so it can protrude below the carriage. The idler bolts no go the other way round so the nuts are captive instead of the heads. 60 mm carriage fan. Spool holders now have tabs for nut traps instead of P clip. Belt lengths corrected and rounded to tooth pitch. Metal pulleys modelled. exploded variable now 0/1 instead of boolean. Dibond version now has mouse holes for wires and the Y wires run underneath the base. Added jigs for inserting Jhead and drilling tubes. Hobbed bolt not shows hob position on the BOM. Everything in the kit is now in the model and so appears on the BOM. Added ribbon cable, wire, heat shrink sleeving, foam spunge, PLA sample. Completed the kit build manual. Sub assemblies restructured to reflect the build order. View files added to make the assembly diagrams. Fixed sheets.py not working first time run.
