FIR heaters might work better than forced air in your application, though SPA/hot tub forced air heaters are also a good option.
Benefit of Far Infrared heaters they mainly heat objects that absorb IR radiation, like opaque plastics. The emmiters themselves stay cool. Aluminum also reflects IR really well. Steel not so much.
Glass will reflect FIR, AKA the greenhouse effect. From what I know, Polycarbonate and plexiglass are better insulators for recirculating hot air boxes.

Annealing (another thermal cycle to release internal stress of material) will get some more strength of the print

For extra strength I anneal PETG parts with a heatgun. I think it doesn't just relieve stress but increase the layer bond (mainly of the "skin"). Layer bond is the main weakness of printed parts.

i found this oven with 25cm^3 chamber, up to 300c and cost about 60usd (w/o shipping). maybe you can have a try.

it's one of the tens of matel processing shops in taobao.com. i havent use it, i mentioed it just based on the price they offered.

taobao is china's ebay. chinese ppl do all 2b or 2c business online. i mean ALL. western ppl usually use aliexpress because of language. i live in taiwan so easier for me to access these materials/products/services. if language is not a problem, choose wisely based on their china style review system, you'll find qualified enough products.

I'm from Eurpe (Spain), and language is indeed a problem, as shipping cost also is. And makerspaces here are almost non-existent, so access to custom metal pieces is kind of difficult.

try aliexpress.com, this is multi-language site for non-chinese ppl. although not all, but many taobao stores are also in aliexpress.com too.
however i think there are definitely local metal processing shops in spain too. send your dwg files and they'll cnc/laser-cut for you. some shops accept hand drawing if parts are simple enough.
