¶ FMDA DD17.2
FMDA's DD17 is a full size Glock Gen3 pistol frame. It is both well proven and serves as the base for many other Glock frames. It supercedes FMDA's original DIY frame and should be compatible with all standard full size Glock models.

The DD17.2 is easy to print, easy to find parts for, easy to assemble when printed correctly, and has a plethora of derivatives. The base model allows for either a Gen3 slide lock spring or a Gen5 one. It also comes with a detailed and easily followed instruction manual.
The DD17.2 has its own set of rails which are meant to be handmachinable using nothing more than a chunk of aluminum and a dremel. Even so, several manufacturers offer steel rails at very reasonable prices.
All combined this makes The DD family an ideal project for a first time builder. A DD17 printed with a glass filled nylon is likely on par with an OEM Glock frame.
¶ History
todo compare the various revisions and look for differences; they don't seem to be documented anywhere public
¶ Build Notes
The front rail should be snug but should slide in without too much resistance. If it requires a great deal of force or some filing to insert the rail your frame is likely too fat, caused by over-extrusion. If the front rail drops in with no resistance or rattles your frame islikely under-extruded.
An over-extruded frame can be filed down to functional. Removing material from the rear rail slot is nearly impossible though, and that makes pinning the rear rail cleanly near impossible. Fortunately the rear rails do not have to be exact--drilling a new hole or pinning them slightly high is an option (which might require more filing due to the slide being angled)
Non-OEM parts are not always to spec and may cause issues. If using cheap parts it's a good idea to work the slide with a lot of oil a couple hundred times to loosen the parts up.
¶ Parts Availability
Glock parts as a whole are widely available due in no small part to the 80% market. Cheap 9mm parts kits in particular are offered by many retailers. Locking blocks often have to be bought separately but they too are easily found.
Rails for the FMDA are the only non-standard part and even those are easily acquired. As it is the most common rail system in the 3d printed market several reputable vendors offer them.
¶ Derivatives
Almost all Glock frame derivatives are derived from one of the FMDA releases and a complete listing would be both time consuming and noisy. Here are some of the more notable variants and variant creators:
- Booligan Custom Gunworks (many variants on odysee profile)
- Auto 17/17L (17L under-barrel extends to slide length, pic rail, modeled after RoboCop)
- Big / Big-ish Chungus (under-barrel weights, beaver tail, under-barrel extends to slide length)
- CyberChungus (under-barrel weights, under-barrel extends to 17L length and down to bottom of trigger guard, cyberpunk look)
- CDD17.2 (Gen4 outer appearance, mag scoop cut, pic rail)
- ChairmanWon's stippled glocks (custom stipplings, 17 and 17L)
- DD17.2 BTPR (Beaver tail + pic rail)
- Digital Nimbus Labs (many variants on odysee profile)
- DNL DD20.1 (gen2-gen4 large frame (that means 10mm/45acp))
- DNL DD17.2 (gen3 and gen4 frame, optional beaver tail stipple and pic rail)
- Doot Defense DD17.2 Wombat Master (stipple, beaver tail, magwell, double undercut)
¶ Accessories
todo I can't think of anything specific here, other than maybe mentioning that standard glock accessories will fit and maybe a mention of all the pic rail frames that exist
