PLUS 4 CONCH HOTEND SPACER PLUS FAN MOVE MOD

DISCLAIMER: This mod is incompatible with the stock Qidi Plus 4 front cover. A modified front cover must be designed if the user wishes to use a front cover.

Some who have purchased the Conch hotend for the Plus 4 have expressed discontent & concern for the design of the heatsink fins. When installed the fins do not rest against the back wall as on the stock hotend. This mod provides a spacer for the fins to rest against. It also moves the stock fan down to increase air flow. 

Printing the design:

It is recommended to print this model with .12mm layer height due to the threaded hole details. 

This model requires a material with a heat deflection temperature such as ABS, ASA or higher to avoid softening when printing parts that require high heat and or a heated chamber. ASA-CF, ASA-GF & PET-GF all were successfully tested over a 3 week period. I prefer PET-GF because its the least expensive filament with the highest heat deflection temp for this application.

You will need to support the area under the fan & if you prefer, some of the circular overhangs. I have modeled in threads to assist in attaching the fan. If you are familiar with the Conch hotend this mod should be a breeze for you but take care not to strip the threads.

.step, .stl & .sldprt (Solidworks) file types are included.

There will be a fan shroud design to go along with this model that will help keep the air flow concentrated through the fins in the near future.
