A remix of Printojet's amazing design. Strong enough to be used without the front bar support with 2 sets of stiff springs. Bolt fork much stronger to cope with sudden joystick end-of travel bumps.
Designed to have no flex with PLA <40% infill.
Be sure to have 4 walls or the joystick nuts can dig into the plastic.
The author remixed this model.
Cleaner bolt fork, washer's won't hit the fillets.
Much stronger bolt fork: removed Allen key holes, reduced bolt wiggle room, created side structures, reduced center cutaway.
