Fence post adapter/reducer - 5" to 3.5"

Cap to sit on top of a 5" (127mm) square vinyl fence post and reduce to a 3.5" (89mm) square post size.

4 centered holes on the print to secure it to the base post, sized as a pilot hole for #10 screw.

This model was designed to be printed with ASA. You may need to tweak/scale it slightly depending on the ASA formula or if you intend to use other material. My prints were done with Polymaker Polylite ASA and I had to account for XY shrinkage of 0.5%.

Print settings I used (GCode available):

• 8mm brim, 0.1mm separation, inner and outer
• 0.2mm layer thickness.
• All walls (should take 4-5 total)
• Cooling fan off
• Nozzle 260C
• Bed 105C
• Chamber 55C (preheat)
• Shrink compensation XY 0.5%
• Limit speed to 50mm/s max and reduce to ~35-40mm/s as it starts the transition to the 3.5" section. Neck transition will delaminate if it goes too fast. You may be able to re-increase the speed once it's climbing straight again depending on your formula's sensitivity to layer time. If you're not sure, play it safe.
• Let this cool in the enclosure to ambient temperature once completed.

Yes, this print will take a while to complete but it's a large hollow object and believe me when I say that going too fast will lead to delamination; it took time to tweak settings for. This will print without supports if you're dialed in well enough but I do not suggest printing without the brim since the wall contact surface is just too narrow..

Gcode included for reference to my settings but remember to never print using other people's gcode!

If you're going to screw into the upper part of the mount make sure you drill pilot holes!
