Looks like I’ll have to go through the whole process again tomorrow. I made the bits for the 30minute X mod today and thought I’d just need to loosen the Makerslide to get the bolts in. As I’m using a steel bar with threaded holes instead of separate nuts, I’ll need to disconnect Makerslide at one end to slide the steel bar into position on the bottom of the Makerslide.
Top piece is 12mm aluminium bar, drilled and countersunk for 8xM5 bolts. Lower part is 32mm mild steel bar drilled and tapped for the M5 bolts. A bit of a cleanup (maybe paint the steel) before installation tomorrow.
