Hidden Electronics Conversion Kit for MendelMax

thingiverse

Initially, I arranged all the components of a MendelMax Reprap in CAD before starting its assembly. I was perplexed about how to neatly accommodate the electronics until I realized there was ample space within the base frame's interior. Consequently, I designed "lifters" alongside split Y-Rod mounts (thing:16019) to conceal power supplies and electronics. To address the concern of Z-axis rigidity due to moving the drive system outside rods, I invested around 20 hours of printing with the longest print lasting 4.5 hours without any issues. Print two sets of each "lifter" type and two belt clamps. Insert M3 nuts into "lifters" (16 pieces), install LM8UU's along with internal snap rings (I used 5/16"), split Y-rods using thing:16019, slide "lifters" onto rods, and attach the belt. Secure a piece of wood, such as 1/4" Baltic Birch, to the base. Install electronics (suitable for switching power supply; standard PC PSUs are too tall), secure with wooden screws and wire clamps, then use liquid nails for additional support. Ensure "lifters" don't hit wires while sliding. Create a "mount plate" using 1/4" Baltic Birch, noting countersunk holes, and attach it to the "lifters" with flat head bolts (16 pieces). Mount your heat bed as desired; my setup is mount plate -> heat bed -> AL plate -> glass. Enjoy your MendelMax Reprap!
