You can order TexasPyro open source boards from OSHPark and if you know how to use a hot air rework station you can do it yourself
Cheapest route is to get the 20mm adapter boards from FT and put a 17mm Nanjg on it…but a full size board would be best
You really don’t need to fill the pill…but a 20mm sinkpad or noctigon then epoxied to the shelf would go ALOT farther than beating yourself trying to fill the pill…
Put some noalox on the pill threads to aid in getting the heat out of the pill to the body
