12MN/mgr Y rail conversion for d-bot 3d printer

thingiverse

Linear rail conversion for d-bot 3D printer uses two 12mm MN12C linear bogies per side on top, eliminating the need for bottom support. One MN12H per side may be a better solution to consider. The f3d file provided can be modified to suit your linear bearing requirements. The "mk1m" model requires printing two parts, one per side. Parts needed per side/support include: a) One M5 x 10mm bolt and two M5 x 12mm bolts with 5mm washers. b) Three M5 tee nuts. c) Eight M3 x 14mm bolts with washers are required. d) Two M3 nuts are needed per support for bearings. e) Two M3 x 30mm bolts are necessary. f) Four F623ZZ standard d-bot belt bearings and 3mm washers are required. On October 1, 2017, the "mk1p" model was added, which is a bit stiffer. The red support is not clear, whereas the clear support is the UV gantry support. The build is currently under test, and the information provided may be incorrect. Use with caution. A Fusion 360 f3d file is available to modify for different rails such as an MGN12H, which could be a better solution. The accuracy of the bogies will determine how much correction is needed. Good quality bogies typically require minimal adjustment, while bad ones can be off by up to 0.7mm. Choosing a reliable linear rail supplier is essential.
