You could start getting into war gaming miniatures... Tanks you can actually afford... I recommend Roco Minitanks, as they're a little bigger and cheap secondhand.
On that tangent...
A GEC and a cheap 3D printer cost about the same, so you might consider that. But be warned, you get what you pay for... Buddy of mine has a nice Bambu he's had zero problems with. Me, a Flashforge Adventurer 5M that consistently makes me want to pull my hair out. Seems every time I get it dialed in and making nice prints without much hassle, the display cable breaks or a part of the print (usually supports) falls off the bed and lands in a hard-to-reach spot and jams something up.
I've been meaning on 3D printing a few tanks and such (which at 1:100, is a little smaller than a Matchbox), and even downloaded a few files. However, that cheap POS Chinese Flashforge keeps having something break with parts that aren't off the shelf--especially the display cable. I'll replace the cable here soon , but else--I'm eventually buying a nicer printer.
I recently printed these two off before the display cable broke when the high-mounted display fell off yet again. My plans are to replace the cable and eventually display here pretty soon (display cable socket lock broke, and the 3D-printed replacement works a little too well--to the point of crimping it).
Both of these maybe cost a quarter total in filament--a Schleich horse at a farm supply store costs $10, and a true 1:64 truck close to ten bucks as well. They'd both probably look better painted, something I plan to do here pretty soon.
It has gotten out of control 
.... 
I think I found a NEW hobby that will be significantly cheaper than blowing all of my hard-earned pay on stupid knives!* 
Anyone one as frustrated as I am?
