Summary

Great project and one of the first parts I designed for an ABS print (which is a "Tricky" material to print due to it not liking part cooling or drafts or temp fluctuations!!

But could be printed with PLA or PETG

Post-Printing

The M10 Hole in the bottom Holder was to attached to a wall backet (not included) These are available at most hardware stores, but "Can be printed" if required.

Only issue is the Holes in the Top and Bottom parts (as they are printed sideways on).

ran a clearance drill through the 5m holes to allow bolts to fit.

I used the following fasteners

6 x M5 x 20mm Hex head domed bolts

3 x Nyloc M5 nuts for Bottom Holder

Top Holder
2 x Nyloc M5 Nuts (still allowing movement, not tight)
1 x M5 Wing Nut to "nip" the Top Holder/slider onto the slider

Works Great!
