I'm far from an expert, but I have been looking into a 3dprinted DL-44 myself.
That is an old model that is for some reason popular but completely inaccurate.
A lot of details fused or exaggerated and a lot of details added from nowhere.
The cheapest 3dprinted version I've come across that is accurate, is this one for $50.
Though they don't have any images of the Kit so I don't know how it assembles or what extra screws and drills you might need.

I believe it may be this model but can't know unless I buy it or ask the seller as they don't have the images of the kit.

If you change your mind about budget though, the one I've been eying is $113.
It's definitely a much steeper price but it has a functional Hammer, Trigger, Bolt and Safety, has all the hardware included, is designed to be upgraded with electronics and has a damn good print quality.
Please note that we are experiencing a surge of orders; we manufacture kits on-demand and delivery times are greatly impacted. Current estimates show new orders will ship in 5 to 6 weeks. Hokey religions and ancient weapons are no match for a good blaster at your side, kid. -- Han Solo 1:1 scale

They also have a number of variations available including Greedo Killer and Merr Son.
The only downside I can spot is that the body is printed in 2 halves so you would have fill that seam if it is too apparent.
Your last option would be to find a model on a site like Thingiverse that you like best and then have it printed by someone on a site like Treatstock.
The downside to that is that due to the size of the Blaster you will probably still be paying around $40+ and it can kind of be hit or miss as not everyone has their printer calibrated for the model...or rather is it the model for their printer."technical stuff that I don't understand"
As a result you can get more imperfections than you would from someone that has printed the same file repeatedly and ironed out the kinks.
