MP Mini Delta Bottom cover with extended legs and fan mount

thingiverse

Update: I made a few very minor tweaks based off my print that pushed the design to Rev 2 and updated the post with photos. My MP Mini Delta is overheating and needs more airflow over the Stepper motor drivers. The stock bottom cover has a hole for a 60mm fan, but no fan is included and I didn't have that size fan. This is a replacement bottom cover I made for the MP Mini Delta. It has mounting holes for a standard 80mm by 25mm PC case fan that I had on hand. It also has extended legs to give the needed height to allow airflow for the fan. I put two sets of screw holes in the design. One set is counterbored to make sure that short screws that hold the stock cover on can reach and the other set are not which makes the screw hole stronger, but needs a longer screw. I printed this on my Prusa mk2 and it just fits on that bed. If you cut it up into 3 pieces you should be able to print it on the MP Mini Delta bed, but I haven't tried. I haven't found an easy way to wire this fan into the main board of the printer so I'm just powering it with a 12v power supply I have on hand, but once I dig a bit more and figure out how to wire it in I'll update this post with instructions. The random extra hole is for the fan wires to get inside. I designed this in OnShape so anyone can easily modify the design by going to the following link and forking the model. Everything is parametric so it should be easy to change the leg height or fan size if that fits your needs better. Please leave a comment if you make a change or improvement so that everyone can gain from it. https://cad.onshape.com/documents/47af9fd0edb2f59787c8471a/w/20fb0c96cbc036b9260822cf/e/1cef293fce2ec463c843a33f
