Reprappro Huxley Z-height gainer

thingiverse

Increase your Z-motor height by 40 mm to move the z-couplings to the printer's upper side, enabling a print height of up to 100 mm. However, note that only an additional 13 mm is achievable if the first collision with the X-axis is the z-couplings. To achieve this, replace your current M5 threaded rods and M3 screws for the z-motor mounts with 40 mm longer versions, and ensure the corners of the z-couplings are rounded or chamfered to allow free rotation in the z-height gainers. Print two sets of these modifications for best results.
