INTRODUCTION: 

The Printsulation Top Hat is an insulated top hat mod in multiple sizes. It is distinguished from other top hat mods in that, except for the 3mm foam tape it is entirely printed. It is also well insulated from the start, and provides mount point for various fixtures, cable management and easily modifiable ingress and egress for cables and filament paths to the print chamber. 

Please familiarize yourself with the print specifications and guidelines for all Printsulation parts, maintained in the Printsulation Side and Top Flat Panels model. I don't repeat them here, as attempting to maintain multiple sources for the same information is a recipe for error.

The full series of models (names link to their pages) is:

• Printsulation Side and Top Flat Panels 
• (This) Printsulation Top Hats 
• Printsulation Side Hats 
• Printsulation Fittings
• Printsulation Test Parts 
   

SAFETY WARNING: Actively heated chambers are a common cause of house fires, especially involving one-off designs without professional QA and testing facilities. DO NOT USE any form of heater that could create hot spots or expose the Printsulation parts to ignition temperatures, including by installation error or by failure of any part or device in or near the printer.
 

FILAMENT CHOICE: Insure that your chamber temperatures never exceed a safe temperature for the filament you use. These panels will help you heat quicker with more energy efficiency regardless of temperature. But there has been insufficient testing, and there will always be too many variables to allow me to recommend a max temperature. 

As for options: If you are capable of printing Polymaker PolyLite PC and can afford it, it is by far the best choice among filaments up to $30/Kg. If not, Polymaker ABS is likely the next best choice, at $20/Kg.

This video with heat deflection testing may help you determine a max safe temperature. 
  

BOM: Developing this system took a great deal of time and money. Please support this project by using an affiliate link to buy your filament and other parts. By using one of my affiliate links to get to Amazon, I will be credited even if you buy a different color or brand.

• Filament:

    - ABS: https://amzn.to/3YVCtpc 
   
• 8mm(w) x 3mm(t) Foam Sealing Tape: https://amzn.to/4dubLYv 
   
• Choose your size (150mm is a good size for most use cases). Print 2 each of the (A) part and (B) part.
   
• Print as many Printsulation Fittings as needed for the portholes and bone joiner spaces. NOTE that there is a “short” variant of the porthole plugs to accommodate slightly warped prints.
   

YOUR SIZE TOP HAT NOT HERE?

Please request it in the “Makes and Comments” tab (above). Please state the printer model it is for, and link to official specs for the size needed. Or link to some evidence for a consensus of the size needed. I don't intend to clutter this with one-off sizes, but will be happy to post new sizes for common or production printers where at least a few people may be interested.
 

HOW TO SUPPORT YOUR FAVORITE DESIGNERS:

• The easiest (free) way to send money to the designer you are supporting, is to simply click an affiliate link to get to Amazon (or other site) whenever you buy something related to their work… Or unrelated even. 
   
• The rules are vague and change occasionally, but in general using an affiliate link to get to Amazon will credit the affiliate/designer a small percentage of sales that happen during that session. So… https://amzn.to/3WqP2WI   :-)   Thanks!
