thingiverse

Part cooling fan mount and shroud for this mount utilizes a 5015 radial fan. Print Settings Printer Brand: RepRap Printer: Prusa i3 Improved for Lasercut Rafts: No Supports: No Resolution: 0.2mm Infill: 25% Notes: Supports are built into the STL for the required parts. Ensure your slicer detects thin walls (I use Slic3r), or they may be missed. Printed in ABS at 230C extruder, 110C heated bed, in a sealed chamber, with 5mm brim. Paused the print right after the brim and before the first layer contours, then applied super-glue where the first layer contours were to be printed. Bed adhesion was so good it actually pulled a few shards of glass off the bed when removing. Zero warping occurred. Post-Printing Removed support materials with a small curved file, cleared the holes with a small rounded file, and sanded the flat surfaces with a sanding block. The air pipe required some effort, but I eventually got it clean. I also forgot to model a little clip on the exhaust of the fan, but a little filing fixed it easily. How I Designed This This is mostly spaghetti code in OpenSCAD. For the HCAD/* libraries check my github repository.
