I still don’t have the instructions written up, but if anyone is interested, here is the SVG. I designed it to be printed on Proofgrade Medium Draftboard (12"x20").
It is still a work in progress as I learn new tricks and methods.
And it does currently require extra hardware that is not printed:
(2) 1.25" #8-32 Machine Screws
(3) #8-32 Machine Screw Nuts
(4) #8 Washers (for spacing on the wheel axel – 1 in the back, 3 in the front)
(4-8) 1/2" diameter Chrome Steel Ball Bearings
(Be aware of those tiny pegs at the top! They fell into the crumb tray the first time I printed them. They are used to pressure fit some of the rails to the ramps.)
If you get it working, please respond back here! I would love to see and hear about your experience!
OH!! Beware those tiny pegs at the top! They fell into the crumb tray the first time I printed them. (They are used to pressure fit some of the rails to the ramps.)
Had a rookie mistake though, I did not have everything aligned right so one section and a few other pieces didn’t cut. I removed successful pieces, then did my best to align the remainder. It worked out ok.
