IMPORTANT: Get the latest updates for this model here on PrusaPrinters.
In 2021, all updates and uploads of new models were moved to PrusaPrinters, of course still free and under the same conditions... :)
The original kit has too much wobble on the Z axis, resulting in shifting and uneven layers.
This design is for a minimal but rigid Z axis, using a trapezoid lead screw. There are only changes to the original design, where needed.
The new replacement parts is printed in ABS. To make the trapezoid threads work properly they needs to be cleaned with a tap (can be homemade).
I plan to make a nylon print of nut block to make the construction more wear resistant and with lower friction, but the friction turned out to be fine in this ABS version.
(NB: Parts shown on the photos are printed before upgrading...)
