This is a jack handle keeper for use with the farm jack available at Harbor Freight(see photos).
My jack is mounted on my Jeep and this piece keeps the handle from rattling around. Print using Ninjaflex filament.
My MP mini has been modified to feed Ninjaflex by using the feed base and arm by robin7331.
I have the extruder fan duct blocked off with tape so no air blows on the piece.
I use masking tape on my bed and coat it with purple Elmers glue stick.
I set the extruder temp at 250c.
I only heat the bed to 50c. If you heat the tape too much it weakens its bond to the build plate, it lifts and your part warps.
No post printing work required. Peel it off the build plate and put it on your jack...that's it.
