40mm block and layer fan adapter for TINA2

thingiverse

UPDATE 2023-JUN-02: Modified the air output of layer fan to aim better to the nozzle. Reliable part. Final design. I don't like 30mm fans (tiny, unreliable and noisy) so designed a 40mm adapter for my little TINA2 that acts somehow also like a layer fan sharing the air to the cooling block and layer cooling. The air from layer cooling doesn't go directly to the nozzle, it goes a little bit before it. You will see it in the design. Not an ideal solution but this is a compact and cheap update if you can't have extra pins on your board or don't want to mess a lot with electronics and firmwares. This was a quick design, as I was in a hurry and had lot of work, so it is not a beatiful design, just functional. But as it was reliable and works fine I leave it as is. Instructions: You just need 3x M3x20 alen bolts and 3x M3 nuts. Beware, bolts should be flat head type, this is important to not impact at X=0 with the extruder motor. Pictures of before and after update provided. Take the wires of the existing 30mm fan or add a JST connector like I did. attach the 3x bolts to the part, use current M3 30mm bolts of the 30mm fan to fix the mount and then the 40mm fan with the 20mm bolts. It doesn not require supports, I made it of silver silk PLA, as it don't suffers from thermals in any way. I spent several weeks trying to make this little printer a piece of cake and designed this mod, along with this: https://www.thingiverse.com/thing:6050289, those make this printer a silent, wonderful companion for the desk of any maker. Seriously, just this two details throws this printer into another segment. I also added a dual gear all metal BMG extruder and since all this mods it outperforms my other printers in quality and noise using PLA and PLA+ materials. I actually encourage you to try this two mods, specially the anti Z-wobble to stop noises and improve print quality. Cheers.
