This is roughly designed after a Hammarlund style vintage form, with some changes. I designed it to accept a common octal plug in tube base:

OD is 1.625", height is 3".
I printed this in PETG. 20% infill, but anything should work fine. Avoid the black filament as it may be carbon bearing and mess up the “Q” of the coil.
I've included the fusion file (f3d) so anyone can modify it.
The coil_form_shorting.stl file is for making a short “coil” that is used to short out the cathode tank circuit if you're using these forms to build a tri-tet transmitter.
The coil_holder.stl file is a handy holder for these octal base coil forms.
If you wish to try your hand at building the transmitter shown in the pictures - here is my write up:
