DL Q33 Sniper Rifle Desk Display Ornament : COD

A non-firing, glue-together desk sculpture of the DL Q33 from Call of Duty: Mobile, designed for FDM printing with no supports. Assembled on its stand it measures 435 x 84 x 105 mm. The largest part is 178 mm long and the tallest print is 159 mm, so everything fits a 180 x 180 x 180 mm printer. Unofficial fan art; Call of Duty and the weapon names belong to Activision. Decorative display model only.

Lore:
The DL Q33 is the bolt-action sniper rifle most Call of Duty: Mobile players learn to quick-scope with. It is one of the game’s original sniper rifles and the first one most players unlock, and it has long been a favourite for its one-shot damage and consistency. Players recognise it as the series’ Intervention, which is to say the CheyTac M200.

Reference geometry:
The M200 silhouette is a string of distinct modules, and the ornament keeps each one: a long tube stock with a butt pad, cheek rest and rear monopod; a compact octagonal receiver with the grip, trigger guard and box magazine hung underneath; a barrel shroud carrying the arched carry handle on top and the bipod yoke below; a long scope on two rings; and a fluted heavy barrel ending in a slotted muzzle brake. At 435 mm it is roughly 30% of the real rifle’s length. It is a stylised interpretation, not a trace of the in-game mesh.

How it is split:

• Chassis, left and right halves (178 mm): receiver, lower chassis, trigger guard, rail and barrel shroud, split on the centre plane. The right half carries the bolt handle as a moulded, non-moving post and knob.

• Stock, left and right halves (120 mm): tube, butt, cheek rest and monopod, with a 13 mm tongue that keys into the back of the chassis.

• Scope, left and right halves: tube, bells, three knurled turrets and both rings. The ring feet drop into two slots in the rail.

• Barrel: one solid 159 mm piece including the muzzle brake, printed muzzle-down.

• Muzzle cap: solid orange plug.

• Carry handle, grip, magazine: separate for colour, each with keyed tenons.

• Bipod: a flat A-frame that keys into the shroud and pegs into the plinth, so the deployed bipod is the front support.

• Stand: a 250 mm plinth in two bed-sized pieces joined by a vertical sliding dovetail, one snap-fit rear cradle, and a nameplate that slides in across the joint and locks the two pieces together.

Joints and tolerances (clearance is per side):

• Alignment pins: 4.00 mm x 9.6 mm pins in 4.40 mm x 5.0 mm deep holes, 0.20 mm.

• Keyed tenons (stock tongue, grip, magazine, carry handle feet, bipod yoke): 6.0 mm thick tenons in sockets, 0.20 mm.

• Barrel seat: 8.0 mm D-spigot in 8.4 mm blind D-socket, 0.20 mm.

• Muzzle cap: 6.0 mm x 4.0 mm D-spigot in 6.4 mm x 4.2 mm blind socket, 0.20 mm.

• Scope ring feet: two 3.0 x 8.0 x 3.0 mm tongues in rail slots, 0.20 mm.

• Bipod feet: 6.0 x 7.0 x 5.0 mm pegs in blind plinth pockets, 0.20 mm.

• Plinth joint: vertical dovetail tab, 14 mm root, 22 mm tip, 10 mm long, 0.25 mm.

• Nameplate: 80 x 24 x 2.4 mm plate with 45 degree bevelled ends in a dovetail groove, 0.25 mm.

• Cradle to plinth: two barbed legs (7.0 mm thick, 0.6 mm barbs) in a 7.4 x 10.4 mm mortise, 0.20 mm.

• Weapon to cradle: 0.6 mm beads on two 2.2 mm spring arms click into 0.7 mm detent pockets.
  If your printer runs tight, do not scale: sand the pins or open the holes with a 4.5 mm drill.

Filament and colours:

• Chassis and stock halves, pins: Matte Charcoal PLA

• Scope, carry handle, bipod, grip, magazine: Matte Black PLA

Assembly:

1. Dry-fit everything first.

2. Pin and glue the chassis halves (six pins), the stock halves (three pins) and the scope halves (two pins). Clamp each.

3. Glue the stock tongue into the rear of the chassis and check it is in line.

4. Glue the barrel spigot into the shroud, flat side down, then glue the orange cap into the muzzle. The cap is permanent by design.

5. Glue the grip, magazine, carry handle and scope into their sockets, and the bipod yoke into the underside of the shroud.

6. Slide the two plinth pieces together vertically, slide the nameplate in from the front to lock the joint, press the rear cradle in until the barbs click.

7. Lower the rifle so the bipod pegs find their pockets and the stock tube snaps into the rear cradle.
